Birthdays: explicit "Birthday calendar" add type + tidier table defaults (web)

- add "Geburtstagskalender" to the sidebar +calendar dropdown and a "+ Geburtstage"
  button to Settings > Calendars; both call ensureBirthdayCalendar (server enforces
  one per account) and toast "already exists" if present
- Settings birthday section: when none exists, just a hint pointing to "+ Geburtstage"
  (creation lives in the add area now, not a separate activate button)
- resizable calendar table: sensible default column widths instead of raw measured
