feat: polish all pages — tooltips, sticky headers, roles, search, AI prompts

Dashboard KPI:
- Fix 1534m → 25h 34m (formatMinutes helper)
- Add info icon tooltips on all KPI and metric cards
- Pass role="admin" to AI panel for manager-specific prompts

Settings:
- Add search + pagination to employee table
- Infer roles from email convention (platform roles API returns null via API key)

AI Assistant:
- Role-specific quick prompts: manager sees "Agent performance", "Missed risks"
- Agent sees "Doctor availability", "Treatment packages"

Sticky headers:
- Add overflow-hidden to campaigns and all-leads pages

Misc:
- Fix free-brands-svg-icons → pro-duotone in integrations
- Remove Follow-ups from CC agent sidebar
- Remove global search from TopBar
