Deferred backlog: attachments, canned responses, tags, search, notifications, password change

Attachments: file storage on the same data volume, serving route with
dual auth (session or portal/widget token, internal-note attachments
never token-servable), inbound ingestion from email (mailparser) and
Telegram (photo/document handlers), outbound delivery via SMTP
attachments and Telegram sendDocument/sendPhoto, upload UI (paperclip +
pending-file chip) on all three reply surfaces. Extracted
lib/tickets/delivery.ts so the text-only and attachment-upload admin
routes share one channel-delivery code path instead of duplicating it.

Canned responses: CRUD + a popover picker in the reply box that inserts
a saved template into the draft.

Tags: fixed 6-color palette reusing existing soft-badge tokens, a picker
on the ticket page, colored chips + a filter row on the dashboard.

Search: LIKE-based (not FTS5 — simpler and sufficient at this volume)
across ticket subject, customer name, and message bodies; a debounced
search box on the dashboard.

Desktop notifications: permission toggle + a background subscriber that
fires for new tickets and customer messages while the tab is hidden,
clicking one navigates to the ticket.

Password change: new account settings page, verifies the current
password before updating.

Nav: gear-menu settings list now includes Шаблоны ответов/Теги/Аккаунт.
