- analytics.ts: Use group_permissions instead of collection_group_memberships
- notifications.ts: Remove non-existent data column
- imports-tools.ts: Remove non-existent type/documentCount/fileCount columns
- emojis.ts: Graceful handling when emojis table doesn't exist
- teams.ts: Remove passkeysEnabled/description/preferences columns
