* add review padding to explore debug replay api calls

* add semantic search model size widget

disables model_size select with n/a text when an embeddings genai provider is selected

* regenerate zone contours and per-zone filter masks on detect resolution change

* treat null as a clear sentinel in buildOverrides so nullable field edits don't snap back

* extract replay config sheet to new component

* add validation and messages for detect settings
