Tweaks (#22656)

* tweak language

* show validation errors in json response

* fix export hwaccel args field in UI

* increase annotation offset consts

* fix save button race conditions, add reset spinner, and fix enrichments profile leak

- Disable both Save and SaveAll buttons while either operation is in progress so users cannot trigger concurrent saves
- Show activity indicator on Reset to Default/Global button during the API call
- Enrichments panes (semantic search, genai, face recognition) now always show base config fields regardless of profile selection in the header dropdown

* fix genai additional_concerns validation error with textarea array widget

The additional_concerns field is list[str] in the backend but was using the textarea widget which produces a string value, causing validation errors.
Created a TextareaArrayWidget that converts between array (one item per line) and textarea display, and switched additional_concerns to use it

* populate and sort global audio filters for all audio labels

* add column labels in profiles view

* enforce a minimum value of 2 for min_initialized

* reuse widget and refactor for multiline

* fix

* change record copy preset to transcode audio to aac
