Terminal connections can now reference a jumpHostIntegrationId on the SSH
integration config; the backend connects to the jump host first and tunnels
to the real target via ssh2's forwardOut(), rather than connecting directly.
Added an ssh_host_keys table and a hostVerifier callback that accepts and
stores a host's fingerprint on first connect, then hard-rejects on any
mismatch on subsequent connects (trust-on-first-use).
Settings previously only ever showed/edited one integration per type, which
silently prevented configuring more than one SSH host at all. Added a
dedicated multi-host SSH section (per-host Save/Test/Delete, Add SSH Host,
and a Jump Host dropdown) so jump-host chaining is actually usable from the UI.

Implements the minimal-viable terminal described in TERMIX_MIGRATION.md
Phase 1a: a real interactive SSH session in the browser over a
WebSocket, using xterm.js on the frontend and ssh2 on the backend.
Reuses ArchNest's existing SSH integrations (host/port/username/
password/privateKey/passphrase) instead of introducing a second,
duplicate host-management system the way Termix has one.
Backend: new /api/terminal WebSocket route (registered via
@fastify/websocket) handling connect/input/resize/disconnect messages,
authenticated via a JWT passed as a query param (browsers can't set
custom headers on the WS handshake). Extracted the integration secret
loader out of routes/integrations.ts into db/secrets.ts so the new
terminal route can reuse it without duplicating the decrypt logic.
Frontend: new Terminal.tsx page listing configured SSH hosts and
rendering an xterm.js terminal wired to the WebSocket; wired into
App.tsx at /terminal. vite.config.ts's dev proxy now forwards
WebSocket upgrades (ws: true) so this works under `npm run dev`.
Verified end-to-end against a real (test) ssh2-based SSH server:
connect, shell banner, keystroke echo, and prompt redraw all worked
correctly over the actual WebSocket protocol.
Deliberately deferred to Phase 1b/1c per the migration doc: jump-host
chaining, tab/split-pane UI, terminal theme/font settings, OPKSSH cert
auth, tmux session monitor, session recording.
