fix journey bugs reported by roel-de-vries (#722-#736)

Mobile UI:
- #722 timeline carousel no longer cut off by BottomNav (uses --bottom-nav-h var)
- #723 scroll-snap-type relaxed to proximity so small swipes no longer skip entries
- #724 defensive padding-bottom fix in JourneySettingsDialog for iOS PWA
- #725 add back/settings buttons + journey title subtitle to mobile activity view
- #726 active entry re-centers after scroll settle; tap inactive card activates
  it (does not jump straight into editor)

Entry editor flow:
- #727 photo uploads queue locally until Save for existing entries too
  (previously fired upload immediately; Cancel silently kept the new photo)
- #728 Cancel/Close with unsaved changes now requires confirm (window.confirm)
- #729 linking a Gallery photo into an entry now copies the row (old MOVE
  behavior meant Remove-from-Entry also nuked the Gallery original)
- #731 addPhoto / addProviderPhoto / linkPhotoToEntry promote skeleton
  entries to concrete 'entry' type when content is added

Permissions:
- #732 updateJourney switched from canEdit to isOwner — editors can still
  edit entries and photos, just not the journey shell (title, cover, status)
- #733 Contributors list gains a per-row remove (X) control with confirm
- #734 my_role is computed server-side and returned with the journey; UI
  gates Settings/Add/Edit/Delete controls based on role
- #736 createOrUpdateJourneyShareLink + deleteJourneyShareLink now require
  isOwner (previously NO permission check at all — anyone authenticated
  could publish or unpublish a journey)

Immich upload (#730):
- migration 111: add users.immich_auto_upload (default 0)
- migration 112: seed provider_field for the toggle (idempotent, FK-safe)
- journey photo upload only mirrors to Immich when the user has opted in
- Settings UI gets a "Mirror journey photos to Immich on upload" checkbox

Test updates:
- JOURNEY-SVC-019 inverted to assert editor cannot update journey settings
- JOURNEY-SHARE-007 now passes userId (owner) to deleteJourneyShareLink
- FE-PAGE-JOURNEYDETAIL-148 inverted to assert photos stay pending until Save
- client/tests still green (2676/2676)

Also fixed en route: gallery entry title is now the literal 'Gallery' on the
wire (used to send the translated label, which broke server-side title === 'Gallery'
checks in non-English locales); confirm interpolation uses {username} single
braces matching the existing i18n runtime; Settings footer uses icon-only
delete/archive buttons on mobile so the row doesn't wrap.
