Ruben Fiszel 7003998a57 fix(auth): tighten token-owner fallback for unscoped tokens (WIN-1978) (#9293)
* fix(auth): reject unscoped tokens with cross-workspace forged owners (WIN-1978)

An unscoped token (workspace_id IS NULL) whose `owner` field references a
user, group, or unprefixed value that is not present in the target
workspace must not authenticate. The previous fallback in the
`u/<username>` branch granted `(is_admin=false, is_operator=true)` when
no `usr` row matched in the target workspace, letting a token holder
who could mutate the `token` table cross workspace boundaries with
operator privileges.

The `g/<groupname>` branch likewise silently accepted any group name as a
"group user", and the no-prefix branch granted operator state from
arbitrary owner strings. Both are now rejected unless the owner matches
a real user/group membership in the target workspace.

Adds an integration regression covering all three forged-owner shapes.

* chore: drop integration regression for auth fallback

The test added in the previous commit relies on a sqlx::query! that
requires offline-cache regeneration; removing per code-review preference
to keep this PR scoped to the auth-layer fix.
