feat(collections): select toolbar — select-all, move/duplicate to another list (#1081)

- The select toggle now sits at the right of the filter row (same height as the
  status/category dropdowns) instead of the top toolbar.
- Select mode gains a "select all / deselect all" toggle and shows even with
  nothing selected yet.
- Selected places can be moved or duplicated into another of your lists via a
  target-list picker (move re-points collection_id; duplicate re-saves the place
  data, carrying description / category / notes / etc.).
- New strings across all 22 locales.
