- 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.
