fix: add missing getHidden() to Log\Context\Repository stub

Laravel 12's queue handler calls getHidden() on the context repository
when releasing unique-job locks after a ModelNotFoundException
(CallQueuedHandler::ensureUniqueJobLockIsReleasedViaContext). Our stub
implemented addHidden, forgetHidden, and allHidden but not getHidden,
so any queued job whose subject was deleted between dispatch and
execution turned a benign ModelNotFoundException into a cluster of
fatal "Call to undefined method" errors.

Add getHidden() mirroring get() for the hidden array. With nothing
writing to the hidden context in a fresh worker, the call returns null
and Laravel's handler silently skips lock cleanup — the intended
no-op-on-empty path.

Add unit coverage for the hidden-array methods.

Fixes #4611
