GET /api/v1/file?id=<server> created an FM stream on the agent stream
and committed real state change (TaskTypeFM dispatched). With JWT
cookie SameSite=Lax a victim's browser would still send the cookie on
a top-level cross-site GET, so an attacker could trick a logged-in
user into opening an FM session on any of their own servers, consuming
resources and triggering the agent's FM machinery without consent.
Mirror the GHSA-8qhj-4f8c-j8qg fix: move the route to POST. SameSite=
Lax cookies are not sent on cross-site POST. Frontend (admin-frontend)
adjusted in a follow-up commit.

createTerminal and createFM correctly check server ownership before
issuing a stream UUID, but terminalStream and fmStream only verified
that the UUID existed. Any authenticated user holding a valid stream
UUID could attach to it, gaining the original creator's live shell or
file-manager session — and the UUID is exposed via URL path (referer
leaks, access logs, browser history, frontend error reporters).
Bind the creator user ID into ioStreamContext at CreateStream time,
expose StreamOwnership and IsStreamAuthorizedForUser, and check
ownership in terminalStream/fmStream before the WebSocket upgrade so a
rejected attempt does not tear down the legitimate stream via defer.
NAT streams are also routed through CreateStream(_, 0); they are not
reachable from /ws/terminal or /ws/file so a sentinel user ID is fine.
