- Add nil UUID checks after mapContentIdToBookhoardUUID in all handlers
- Add ContentType detection for Kobo EPUB/PDF sync (EPUB=6, PDF=5)
- Add "last-read-place" bookmark type support with EPUB CFI position tracking
- Restore broken mapContentIdToBookhoardUUID function with UUID parsing
- Restore mapBookhoardUUIDToKoboContentId helper function
- Restore getCollectionMetadataForBook helper function
This fixes the catastrophic file corruption from commit 2200720 which
deleted 414 lines and inserted code in the wrong location.
Phase 1-3 of KOBO_IMPLEMENTATION_PLAN.md completed:
- Step 4: Nil UUID checks in Markup, Bookmark, AnalyticsGettests, SyncFromServer
- Step 5: ContentType field added to KoboReadingSync struct
- Step 6: last-read-place case added to Markup handler switch statement
Testing: Code compiles successfully, all handlers properly structured
