feat: improve connector popup with grouped OAuth connectors

Active Connectors tab:
- Group OAuth connectors by type (Gmail, Google Drive, etc.)
- Show account count badge on grouped cards
- Show most recent last indexed date across all accounts
- Show non-OAuth connectors individually with active task messages

All Connectors tab:
- Show most recent last indexed date for OAuth connector types
- Check if any account is indexing for OAuth types

Accounts List View:
- Remove document count from individual account cards
- Back button returns to previous tab (not always All Connectors)

General:
- Update handleViewAccountsList to use (connectorType, connectorTitle) signature
- Consistent behavior for viewing accounts from both tabs
