feat: migrate BookmarkListEvent from kind 30001 to 10003

Rename the existing BookmarkListEvent (kind 30001) to OldBookmarkListEvent
and create a new BookmarkListEvent with kind 10003 as per the updated spec.

- OldBookmarkListEvent (kind 30001): Kept as-is for backward compatibility,
  displayed as "Old Bookmarks" in the Bookmark Lists screen
- BookmarkListEvent (kind 10003): New replaceable event, all new bookmark
  operations (save/check/remove) use this kind
- Both kinds are displayed as separate items in the Bookmark Lists screen
- Old Bookmarks screen includes a "Move All to New Bookmarks" button that
  migrates public bookmarks to public and private to private
- Created PrivateReplaceableTagArrayEvent base class for replaceable events
  with encrypted private tags (kind 10003 is in the 10000-19999 range)
- Updated all relay filters, search queries, and profile views to fetch
  both kinds
- Updated Android and Desktop modules
