Calendar: show the year (fix "can't navigate past 2026")

Navigation was unbounded, but headers only showed the month name so the
year change was invisible and future months felt unreachable.

- Main calendar header now shows "Month Year".
- Date-picker grid label shows the year.
- Year view gets a chevron year navigator (unbounded) + year label.
