The recipient colour was stored on calendar_shares, so it only worked for
DIRECT shares. A calendar made visible through a group (a co-member's
group_visible_calendar_id) has no CalendarShare row, so the colour endpoint
returned 403 and nothing was saved — the reported "colour picker opens but the
colour stays the same" for a group-shared calendar.
Replace the share-scoped colour with a general per-user override table
(calendar_color_prefs, keyed by user+calendar). PUT /calendars/{id}/color now
accepts any calendar the user can read (readable_local_calendar_ids covers
direct shares, group calendars AND group-visible), and the merge read + calendar
list apply the override for all of them. Owners still set the shared colour.
The new table is created by create_all; the old calendar_shares.color is unused.

A share recipient couldn't change anything on a shared calendar (update_calendar
is owner-only → 404), yet the clients still showed a colour picker for it.
Add a per-recipient colour: new nullable calendar_shares.color column (+ migration).
New PUT /calendars/{id}/color endpoint sets the calendar colour for the owner
(global) or, for a recipient, only their own share colour — never the name, so
recipients can recolour but not rename. The merge read and the calendar list now
prefer the recipient's share colour over the owner's (NULL = owner's colour).

- Backend: co-member group_visible calendars now surface in /local/calendars
(owned=false, shared_by=owner, read-only, group_shared) and in the normal
/caldav/events merge (via readable_local_calendar_ids), deduped against
direct shares / group calendars so nothing appears twice.
- Backend: new User.directory_hidden — a user can hide from sharing/group
pickers (/users/directory), while admin user management (/users/) still lists
them. Migration + profile GET/PUT.
- Backend: /groups/{id} members carry shares_calendar so clients can drop
phantom rows for members who share nothing.
- Frontend: reachable "Teilen" button on owned local calendars; share modal is
now a checkbox multi-select of users (checked = shared). Hidden-profile toggle
in Settings → Profile. Group member filter only lists members who actually
share (phantom fix). Calendars shared with me moved to a dedicated read-only
"shared with me" section in the manage table.
- Tests: group_visible propagation, no-share absence, dedup, directory_hidden.

- dav_router: add Basic-Auth principal-discovery tree at /caldav/ (and
/.well-known/caldav) so clients can add a CalDAV account with server URL +
username + password; lists all published calendars. Token URL /dav/{token}/
still works without login. Handlers generalised over a base href.
- dav_util: derive the public origin from X-Forwarded-Proto/-Host (or
PUBLIC_BASE_URL) so published URLs are https, not internal http:8080.
- local_router: expose caldav_login_url alongside caldav_url.
- frontend/i18n: show both the no-login token URL and the login URL + hint.

Backend:
- LocalCalendar gains caldav_published + dav_token + dav_ctag; LocalEvent gains
etag (migrations in main.py). bump_dav() refreshes ctag/etag on every local
event write (create/update/delete/import).
- local_router: PUT /calendars/{id} accepts caldav_published (mints/revokes
token), new POST /calendars/{id}/dav-token/rotate, _cal_dict exposes
caldav_published + caldav_url.
- New dav_router mounted at root (/dav/{token}/...): a minimal two-way CalDAV
server (OPTIONS/PROPFIND/REPORT/GET/PUT/DELETE) reusing ical_io build/parse,
ctag-based change detection. Secret token = auth, no login.
Frontend:
- Settings calendar table: per-local-calendar publish toggle + subscribe URL
with copy and token-rotate; i18n (de/en) and styling.
Note: reverse proxy must allow WebDAV methods (PROPFIND/REPORT/PUT/DELETE).
VALARM/reminders are not round-tripped via CalDAV.

New boolean column on every calendar type (CalDAV, local, Google, Home
Assistant, iCal subscription), default ON so existing data is unchanged.
Lets a calendar be shown without generating reminders/notifications.
- models.py: reminders_enabled on the five calendar models
- main.py _migrate(): ALTER TABLE ADD COLUMN for each table
- caldav/google/homeassistant/local/ical routers: expose the flag in the
calendar serialization and accept it in the calendar/subscription update
endpoints
Clients map event -> (source, calendar_id) -> reminders_enabled to skip
scheduling notifications for disabled calendars.

local_events gains a `reminders` TEXT column (comma-separated minutes-before-
start, like exdate); EventCreate/EventUpdate accept a `reminders: [int]` list
and build_local_event_dict emits it back as a list. user_settings gains
`default_reminder_minutes` (nullable int, null = off), exposed/updatable via
/api/settings (explicit null persists as off). Migrations added in _migrate().
Clients (iOS/Android) schedule the OS notifications locally from these.

Findings from the security review:
- HIGH: private local events leaked in full (title/location/description) to
anyone who could READ a shared or group calendar via GET /api/caldav/events —
the private_event_visibility rule was only enforced in /groups/{id}/combined.
Now enforced in the merge read too, via a shared helper (apply_event_privacy)
so the two paths can't drift.
- HIGH: 'busy' masking was a blacklist that still leaked creator identity,
source-calendar name, recurrence rule and per-event colour. Replaced with a
whitelist (mask_busy_event): only timing/identity/render fields survive.
- MEDIUM: .ics import had no size limit (raw = await file.read()) → memory DoS.
Now capped at 5 MB (413), read before creating any calendar.
- LOW/INFO: profile email now checked for uniqueness + basic format; display
name / username / email length-capped and control-chars stripped.
Deferred (tracked): RRULE expansion cap at the trust boundary, SQLite
PRAGMA foreign_keys + ON DELETE cascade, and JWT-by-user-id + token version.

- Monatsmarker ("JUN") sitzt jetzt inline neben der Tageszahl ("1 JUN") statt
darüber -> einheitliche Zeilenhöhe; Termine der Woche rutschen nicht mehr
nach unten und überlappen nicht mehr mit "+X weitere".
- Gruppenkalender erscheint in "Meine Kalender" (mit 👥-Markierung) und kann
aus-/eingeblendet werden; Besitzer kann ihn umfärben. Recolor fremder
Kalender abgefangen (nur Besitzer). Version v36.

- Sidebar: eine flache Kalenderliste statt Quellen-Gruppen; Quelle/Konto
klein-grau inline rechts neben dem Namen; per Drag&Drop sortierbar
(Reihenfolge pro Geraet in localStorage).
- Gruppenkalender serverseitig auch beim Besitzer als group:true markiert
-> erscheint nicht mehr in der "Fuer Gruppen sichtbar"-Auswahl und nicht
in der normalen Kalenderliste (nur unter Gruppen).
- Settings-URL-State: uiSettingsOpen wird beim Init aus der URL gesetzt,
bevor das erste writeUrlState() es ueberschreibt -> Reload bleibt jetzt
wirklich in den Einstellungen.
- Auswahl-Markierungen (Mitglieder/Gruppen-Sichtbar) in Akzentfarbe,
CSS-gezeichnet statt blauer Emoji. Version v28.

- Import: Dedupe doppelter UIDs innerhalb der Datei (Nextcloud exportiert
wiederkehrende Termine als mehrere VEVENTs gleicher UID) -> kein
UNIQUE-constraint-500 mehr; Commit abgesichert. Test ergaenzt (15 gruen).
- Picker (Gruppen-Sichtbarkeit + Mitglieder): als <div>-Zeilen statt <label>,
damit die globale ".form-group label"-Uppercase/Grau-Regel das Layout nicht
mehr zerschiesst. Saubere .pick-row-Optik (Checkbox/Radio links, Name links).
- Einstellungen haben jetzt eigenen URL-State (#...&settings=1): Reload/Cache-
leeren bleibt in den Einstellungen statt zur Kalenderansicht zu springen.
- Version v27.

- Sidebar-Sektion "Gruppen": Liste, Erstellen (Name + Mitglieder-Picker),
Verwalten (Mitglieder hinzufuegen/entfernen), Loeschen.
- Gruppenansicht: laedt /api/groups/{id}/combined fuer den sichtbaren
Bereich; Event-Titel werden mit Besitzer-Initialen bzw. Gruppen-Icon
praefixt; Banner mit "Gruppenansicht verlassen".
- Server: GET /api/local/calendars liefert nun auch Gruppenkalender
(group:true, read_write) fuer Mitglieder, damit sie im Editor waehlbar
sind. Test ergaenzt (13 gruen).
