fix: report empty projects as not locked
GET /projects/{id}/locked returned True for a project with no drawings
or nodes: both loops ran zero times and the fallback return won. Locking
and unlocking such a project always succeeded while the state stayed
"locked", so it could never be unlocked.

Report a project with nothing to lock as not locked, and re-check the
state after unlock in the route tests.
