* add missing translations and translate page titles

* fix: actually use the declared localized variables

* lint and prettier fixes

* add missing translations for toasts and confirms

* use components for shift/enter keys, add pluralization for photos, and fix primary photo conditional

* remove prop defaults since we're computing these anyways
