feat: Add user settings to disable auto tagging/summarization (#2275)

* feat: Add per-user settings to disable auto-tagging and auto-summarization

This commit adds user-level controls for AI features when they are enabled
on the server. Users can now toggle auto-tagging and auto-summarization
on/off from the AI Settings page.

Changes:
- Added autoTaggingEnabled and autoSummarizationEnabled fields to user table
- Updated user settings schemas and API endpoints to handle new fields
- Modified inference workers to check user preferences before processing
- Added toggle switches to AI Settings page (only visible when server has features enabled)
- Generated database migration for new fields
- Exposed enableAutoTagging and enableAutoSummarization in client config

The settings default to null (use server default). When explicitly set to false,
the user's bookmarks will skip the respective AI processing.

* revert migration

* i18n
