The per-engine concurrency-overrides table on the Settings page already
exposes max_parallel_requests per engine; add a "GPU power lock" column
(dpm level select) so dpm_force_performance_level_overrides is editable
too. Backend: GET returns the map, POST saves it via a level-validating
sanitizer. Takes effect on engine restart.
