refactor: remove deprecated kind-specific cache tables and hooks

Clean up old caching infrastructure now that generic cache is in place:

Database changes:
- Mark relayLists and blossomServers tables as deprecated
- Remove tables from v16 schema (set to null for deletion)
- Keep table definitions for backward compatibility with old versions
- Mark CachedRelayList and CachedBlossomServerList interfaces as deprecated

Removed deprecated hooks:
- Delete useRelayListCacheSync.ts (no longer needed)
- Delete useBlossomServerCacheSync.ts (no longer needed)
- All caching now handled by useReplaceableEventCacheSync

Migration path:
- Old databases will automatically migrate to replaceableEvents table
- Wrapper classes (RelayListCache, BlossomServerCache) still work
- No breaking changes to consuming code
