feat: dashboard restructure, integrations, settings, UI fixes

Dashboard:
- Split into components (kpi-cards, agent-table, missed-queue)
- Add collapsible AI panel on right (same pattern as Call Desk)
- Add tabs: Agent Performance | Missed Queue | Campaigns
- Date range filter in header

Integrations page:
- Ozonetel (connected), WhatsApp, Facebook, Google, Instagram, Website, Email
- Status badges, config details, webhook URL with copy button

Settings page:
- Employee table from workspaceMembers GraphQL query
- Name, email, roles, status, reset password action

Fixes:
- Fix CALLS_QUERY: callerNumber needs { primaryPhoneNumber }, recordingUrl → recording { primaryLinkUrl }
- Remove duplicate AI Assistant header
- Remove Follow-ups from CC agent sidebar (already in worklist tabs)
- Remove global search from TopBar (decorative, unused)
- Slim down TopBar height
- Fix search/table gap in worklist
- Add brand border to active nav item
