direct: fail bind when the deployment state cannot be read

[denik]

bundle deployment bind treated any failure to open the state as "resource not bound": it skipped the already-managed check, bound over state whose ownership was never verified, and overwrote it — while reporting success. A crashed deploy that left a WAL behind was enough to trigger this.

A state file that does not exist opens as an empty one, so the absence of a binding is already covered by a successful open. Return the error instead.

Tests

New acceptance test that deploys a job, leaves a WAL from a different lineage next to the state, and binds: it used to print "Successfully bound" and replace the state file.
