LLM clients transcribing the console WebSocket URL into shell commands
reliably corrupted the ~200-char JWT embedded in it (dropped header
segment -> "MissingAlgorithmError: Missing 'alg' value in header" on
every connection attempt). The node_console tool now mints a short
random ticket ("gns3t_" + 16 urlsafe chars, 10 min TTL, multi-use)
stored server-side and bound to the node's console endpoints:
- new ConsoleTicketService (gns3server/services/console_tickets.py),
in-memory store with lazy expiry sweeps
- get_current_active_user_from_websocket redeems tickets through the
existing "token" query parameter, gated on websocket.path_params so a
ticket only authenticates the console/ws and console/vnc routes of
the node it was minted for; the JWT path is unchanged
- redemption reuses the existing user lookup, token_version revocation
and is_active checks, so logging out invalidates outstanding tickets
- vnc_url no longer embeds the full session JWT
- the tool docstring now tells clients to run the returned command
verbatim instead of reconstructing the URL
