feat(mobile): map view (#3661)

* feat(mobile): map page - add map view

* map: add map-markers

* feat(map): add relative date filter

* fix: do not let users scroll past map bounds

* fix: fetch relative date from store to state on init

* feat(mobile):re-fetch markers only on filter change

* feat(mobile) - asset bottom sheet in map page

* feat(mobile): display markers based on bottom sheet scroll

* fix: exif-bottom-sheet - rebase conflict

* feat(mobile): map-view - strongly typed map page events

* feat(map): zoom to asset

* chore: dart analyzer fixes

* map-page move attribution to top-right

* feat(mobile): map view - asset selection handling

* feat(mobile): map-view display map in places row

* fix: make asset marker icon responsive

* optimise map page rebuilds

* refactor(mobile): map page

* feat(mobile): map-view: Go to location

* map-view(mobile): minor refactor

* fix(mobile): Handle invalid coords gracefully

* small styling
