- Event popup: new "Reminders" section for local events — show/add/remove
multiple reminders, prefilled with the global default on new events; sent
in the local create/update body and synced like any other event field.
- Sidebar calendar list: per-calendar reminder bell toggle (PUTs the new
reminders_enabled flag); disabled state shown dimmed.
- Date picker: a day click now commits immediately in date-only mode instead
of requiring an extra "Save" click.
- Start/End: moving the end before the start now shifts the start back
(mirroring the start handler) instead of showing an error toast.
- Calendar dropdown: group calendars moved under a "Groups" optgroup; dropped
the 👥 emoji prefix (a native <select> can't render the icon SVG).
- Month grid: selectedDate defaults to today so the highlight no longer
follows the cells while navigating before any click.
- Today cell tint now derives from --today-color instead of hardcoded blue.
- version v44 -> v45.
