Settings UI fixes (#23237)

* detector UI fixes

- derive detector and model from memo rather than using two drain useeffects
- sanitize save payload through sanitizeSectionData to prevent yaml validation issues

* increase display duration for restart required toasts

* mimic logic in detector section for save all button

also, increase toast duration for restart required toasts

* fixes and tweaks

- use section hidden fields for sanitization instead of duplicating code
- use parent hooks so save all, pending data, and the status dots work correctly
