feat: PageHeader component + refactor all 6 list pages

New reusable PageHeader component (src/components/layout/page-header.tsx)
with consistent layout: title + badge + subtitle on left, controls on
right, optional tabs below with no extra borders.

Refactored pages:
 - All Leads: inline header → PageHeader
 - Contacts: inline header → PageHeader
 - Appointments v2: inline header → PageHeader with tabs
 - Call History: removed p-7 wrapper + TableCard.Root → flat table
 - Patients: removed p-7 wrapper + TableCard.Root → flat table
 - Missed Calls: removed TopBar → PageHeader with tabs

All pages now share identical header spacing, font sizing, and
control alignment. No more double borders from tab + container.
