feat(collections): bulk-add selected trip places to a list (#1081)

Add a "Save to collection" action to the trip place list's selection bar (next to
bulk category + delete): it opens a list picker and copies every selected place
into the chosen list in one request, instead of one-by-one from each place.

- Server: saveFromTripPlaces (one access check + one WS notify), POST
  places/from-trip-many; dedups by name/coords, skips missing ids, honours force.
- Client: saveFromTripMany api + SaveTripPlacesToListModal; the selection-bar
  button is gated on the collections addon being enabled.
- Copy count / skipped-duplicates toast; strings in all 22 locales.
- Service + controller tests for the bulk path.
