feat: bucket list POIs with auto-search + optional dates — closes #105

- Bucket list now supports POIs (not just countries): add any place
  with auto-search via Google Places / Nominatim
- Optional target date (month/year) via CustomSelect dropdowns
- New target_date field on bucket_list table (DB migration)
- Server PUT route supports updating all fields
- Country bucket modal: date dropdowns default to empty
- CustomSelect: auto-opens upward when near bottom of viewport
- Search results open upward in the bucket add form
- i18n keys for DE and EN
