fix: address PR review feedback

- Show error notification on setup failure instead of silent reset
- Fix toggleKind stale closure by using prop array directly
- Remove duplicate translations from en-gb.json (falls back to en.json)
- Align seed board columnCount to 12 (codebase default)
- Extract shared placeAllWidgetsAsync helper to @homarr/db/queries
- Remove redundant onboardingFormSchema; reuse formSchema for both paths
- Fix lint errors (optional chain, unused imports, unnecessary conditions)
