iOS: complete bundle ID + team ID migration to com.myhoneydue.*

Carries the rebrand from the backend (APPLE_CLIENT_ID, APNS_TOPIC) all
the way through the iOS targets:

- All target PRODUCT_BUNDLE_IDENTIFIERs: com.tt.honeyDue.* → com.myhoneydue.honeyDue.*
- DEVELOPMENT_TEAM: V3PF3M6B6U → X86BR9WTLD (across every target)
- APP_GROUP_IDENTIFIER: group.com.tt.honeyDue.* → group.com.myhoneydue.honeyDue.*
- BGTaskSchedulerPermittedIdentifiers + BackgroundTaskManager constant
- KeychainHelper service identifier
- StoreKit fallback product IDs + Info.plist IAP product ID keys
- ExportOptions.plist teamID
- NSCamera / NSPhotoLibrary usage descriptions reworded
- Onboarding suggestion strings reworked (new %lld%% match copy,
  dropped old "Great match" / "Good match" / "Generating suggestions"
  strings — replaced by relevance-percentage labels)
- xctestplan + settings.local.json housekeeping

App-group rename means UserDefaults / shared-container data written to
the old group ID is abandoned. Acceptable since this is pre-launch.
