feat(ios): saved queries on iPhone and iPad, synced with the Mac

[datlechin]

Summary

• iOS gets saved queries. Query menu > Saved Queries lists this connection's queries and the global ones, in their folders, with search. Tapping one replaces the editor text and never runs it.
• Query menu > Save Query… saves the editor text with a name, keyword and Global switch. Queries and folders rename, edit, move and delete from the list, through context menus and swipes.
• iCloud Sync pulls and pushes SQLFavorite and SQLFavoriteFolder with the Mac's rules: one keyword per connection, the older query keeps a contested keyword, 900 KB limit. An existing install refetches once, since its change token already passed these records. No CloudKit schema change: both types are already in production.
• .tablepro import reviews and imports saved queries as the Mac does, and the result alert counts them. Export gets Include Saved Queries and Also include global saved queries.
• The rules both apps must agree on move to TableProCore: keyword winner, keyword availability, import placement, folder outline, record mapping. The Mac resolver and import path now call them.
• A saved query or folder moved to the sample connection stays in iCloud as it was, as on the Mac, instead of being deleted there.
• Fixed on iOS: a sync whose local write failed still saved the change token, so those changes never came back.
• Fixed on iOS: a pull brought back a record deleted on this device before the deletion was pushed.
• Fixed on Mac: turning a sync category on did not refetch records skipped while it was off. Added and edited records now come back; a deletion made elsewhere while it was off still does not.

Test plan

• New, failing on main: TableProCore SyncRecordMapperSavedQueryTests, SavedQueryKeywordResolverTests, SavedQueryOutlineTests, SavedQueryImportPlacementTests, SavedQueryCodingTests, SavedQueryLedgerTests (keyword availability). iOS SavedQueryLibraryTests, SavedQueryRemoteMergeTests, SyncedWriteFailureTests, AppStateSyncWiringTests, SavedQueryDraftTests, MobileImportOutcomeMessageTests, new cases in IOSSyncCoordinatorTests and DeletedConnectionPurgeTests. Mac SyncCategoryRefetchTests.
• Tests that pinned the old behavior, changed on purpose: IOSConnectionImportServiceTests (savedQueriesAreIgnored is now savedQueriesImport; a duplicate offers Keep Existing when the file holds its queries), IOSConnectionExportServiceTests (saved-query keys left out only when there are none), SyncFieldParityTests (both saved-query field enums are now shared record types), IOSSyncCoordinatorTests (fixture apply callbacks return Bool).
• Simulator build: imported a .tablepro with three saved queries, saved one from the editor, made a folder and moved it there, opened it in the editor, opened the export sheet.
• Not run: Mac to iPhone and back over real iCloud. The simulator has no iCloud account.
