PVBLIC Foundation f685e58833 fix: Preserve arrays in metadata + refresh OAuth token before sync
1. process_metadata (vector/utils.py):
   - Lists/arrays now preserved as-is (Pinecone supports native arrays)
   - Only datetime and dict types converted to strings
   - Enables Pinecone queries like: filter: {labels: {$in: ['SENT']}}
   - Fixed iteration bug (was modifying dict while iterating)

2. _sync_user_periodic (gmail_auto_sync.py):
   - Now uses OAuth manager to get/refresh token before sync
   - Prevents 'OAuth token expired' errors during attachment fetching
   - Falls back to stored token if refresh fails

Gmail Auto-Sync Orchestrator
This module orchestrates the automatic Gmail sync when users sign up with Google OAuth.
Flow:
1. User signs up/logs in with Google OAuth (with Gmail scopes)
2. OAuth callback triggers this auto-sync
3. Background task fetches all emails from Gmail
4. Processes and indexes to Pinecone using existing infrastructure
5. User's inbox is ready for semantic search
Components Used:
- GmailFetcher: Fetch emails from Gmail API
- GmailProcessor: Parse email data
- GmailIndexer: Chunk, embed, and format for Pinecone
- PineconeManager: Background upsert to Pinecone
- Uses existing chat summary infrastructure
