Rework birthdays to a single calendar + UI fixes (web)

- one dedicated birthday calendar per user; enable it in Settings > Calendars
  (or from the New-birthday dialog) — it then shows in the sidebar like any
  calendar (colour/visibility)
- New-birthday dialog: no target picker; day/month selects + a year field that
  hides when "year unknown"; fixed the year-unknown checkbox layout
- create split-button is now one seamless pill; the caret opens the menu
- Settings > Calendars gains a Birthdays section (enable + notify-days-before)
- removed the birthday toggle from the generic new-calendar modal
- profile settings: right-align the section save button for consistency
- bump service-worker cache to v25 so assets refresh
