The combined month view now always includes a read-only "Birthdays"
calendar (ref "@birthdays"), generated on the fly from every contact's
BDAY field across the user's address books — no calendar objects are
stored for it. Each birthday appears as an all-day event titled
"🎂 Name (Age)" (age omitted if BDAY has no year, e.g. "--MM-DD"), colored
pink, and links to the contact's edit page instead of an event editor.
Handles both "YYYY-MM-DD"/"YYYYMMDD" and year-less vCard BDAY formats,
and skips Feb 29 birthdays in non-leap years.

- Combine own and shared calendars into a single /web/calendar month
view, each event colored per its source calendar.
- New event creation now uses a calendar <select> (only writable
calendars offered); editing keeps the event's original calendar fixed.
- Shared calendars use an "owner~name" reference in URLs, resolved via
resolveCalRef which also enforces read/write permissions from
calendar_shares (read-only shares can view/export but not edit/delete).
- Add per-calendar ICS export (single event and export-all) and import,
splitting multi-VEVENT uploads into individual stored objects while
preserving VTIMEZONE definitions and source VERSION/PRODID.

- List of the user's own calendars (web/calendar)
- Month view per calendar with a Monday-first 6-week grid, showing
all-day and timed events, colored dot matching the calendar's color
- Navigation between months (prev/next/today) via query params
- Create/edit/delete events: title, description, location, all-day
toggle, start/end date+time
- Clicking a day cell prefills a new all-day event on that date; the
"New event" button defaults to a one-hour slot starting next full hour
- Deleting an event or invalid time ranges (end before/equal start) are
validated with inline error messages
- Verified round-trip with the real CalDAV protocol handler (events
created via the web UI are correctly visible to a REPORT query)
