Three bugs fixed:
1. TCP stream fragmentation — guacd→browser data pipe treated each TCP
chunk as a complete instruction. TCP is a stream protocol; instructions
WILL be split across chunks (especially display/image data). Added
instruction buffer that accumulates data and only forwards complete
instructions (terminated by ';').
2. Missing client.onerror — when guacd fails the RDP connection (NLA,
auth, TLS), it sends a Guacamole error instruction. No handler was
registered, so errors were silently swallowed. User saw blank canvas
with no feedback. Now surfaces errors via console and gateway callback.
3. Missing client.onstatechange — no connection state tracking. Added
state transition logging for diagnostics.
Also improved CONNECT handshake logging to surface connection parameters
(host, port, user, domain, security mode) without exposing passwords.

SFTP: Added console logging to diagnose, plus a watcher that sends
the pending list when sessionId becomes available (covers the race
where WS opens before sessionId is set).
RDP: connectHost() was returning early for non-SSH protocols.
Removed the guard and use host.protocol instead of hardcoded 'ssh'.

The list('/') call fired immediately after connect(), but the
WebSocket was still in CONNECTING state so send() silently dropped
the message. Now buffers the initial list request and sends it
in the onopen callback.

When replaceSession changed the session ID from pending-XXX to a
real UUID, Vue's :key="session.id" treated it as a new element,
destroyed and recreated TerminalInstance, which called connectToHost
again, got another UUID, replaced again — infinite loop.
Added a stable `key` field to sessions that never changes after
creation, used as the Vue :key instead of the mutable `id`.

When SSH connection fails, close the WebSocket immediately and
auto-remove the pending session after 3 seconds so the user sees
the error message before the panel clears. Prevents stuck sessions.

NPM forwards /api/* correctly but silently drops WebSocket upgrades on
/ws/* despite toggle being enabled and custom nginx config. Moving
gateways to /api/ws/terminal and /api/ws/sftp so they ride the same
proxy rules that already work for REST endpoints.

Root cause: TerminalInstance.onMounted() called sessions.removeSession()
on the pending session, dropping sessions.length to 0. SessionContainer's
v-if="hasSessions" went false, unmounting the entire terminal UI before
the WebSocket could establish and add the real session.
Fix: Added replaceSession() to session store. TerminalInstance no longer
removes the pending session — instead passes its ID to connectToHost(),
which swaps it in-place when the backend responds with the real session ID.
