New admin "Messages" page — a three-pane mail viewer over the mail picpeak
already stores, feature-flagged behind `messaging` (default off):
- Sidebar account tree: All mail / Customers (hello@) / Accounting (rechnungen@)
/ Automated (no-reply@), matching the agreed IA.
- Automated + All Sent = email_queue (listQueue); Accounting + All Inbox =
received_emails (listReceived). Customers folders show an explanatory empty
state pending the hello@ mailbox (Phase 2).
- Reading pane renders the sent body from rendered_html (migration 119) in a
sandboxed iframe; new GET /admin/email/queue/:id returns body + cc +
attachment filenames (disk paths never exposed).
- Received supplier invoices: envelope + rasterized PDF viewer reusing the
accounting inbound blob endpoint, plus "Open in Accounting inbox".
- Context toolbar (Reply/Forward/Create Quote-Contract-Gallery-Invoice /
Book-as-expense-Re-bill) present but disabled — wired in later phases.
Reuses email.service, accounting inbound blob endpoint, RequireFeature +
PermissionGate (email.view), Tailwind dark: theming. No schema change.
