📊 A smarter command center

Another one for the changelog — a small upgrade with a real payoff: full admin.

Analytics dashboard + tags/users/messages CRUD.

What's new

• Role-based admin (users.role + ADMIN_EMAILS allowlist), requireAdmin guard
• Admin layout with sidebar nav + Admin badge; Admin link in owner dashboard
• Overview: KPI stat cards, 14-day scans bar chart, status bars, recent activity
• Tags: searchable/filterable table, bulk generate, per-tag scan/msg counts
• Tag detail: premium TagCard + edit (status/color/tracker), reassign/unclaim owner,
• Users: table + search, role promote/demote, owned tags, delete user
• Messages: all finder messages, read toggle, delete, unread filter
• admin-actions.ts server actions, all requireAdmin-guarded
• Fix: avoid correlated subquery on un-joined query (Postgres column binding)
