Add ultra-concise database methods to PlatformServiceMixin

- Add (), (), () for shortest possible database calls
- Add (), () for query+mapping combinations
- Add (), (), () specialized shortcuts
- Apply TypeScript declaration merging to eliminate type assertions
- Reduce HomeView database calls from 3 lines to 1 line (64% reduction)
- Convert settings loading from 6 lines to 4 lines (44% reduction)
- Replace all (this as any) type assertions with proper typing
