Subject: [PATCH] feat: share location channel invites via the system share
 sheet (#1513)

* feat: share location channel invites via the system share sheet

Adds text-first geohash invites (deep link + App Store URL) from
channel rows and the active-channel header, with an OpSec warning
for neighborhood-or-finer cells.

Closes #1497

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix: add Localizable.xcstrings entries for channel share copy

Cover all six new share/done keys across the 30-locale catalog so
LocalizationCoverageTests and non-English builds stop falling back
to English defaults.

Co-authored-by: Cursor <cursoragent@cursor.com>

* chore: retrigger CI after unrelated VoiceRecorder flake
