refactor: remove all eslint-disable statements and fix underlying issues

- Replace @typescript-eslint/no-explicit-any with proper Filter type from nostr-tools/filter in dataFetch.ts and helpers.ts
- Replace @typescript-eslint/no-explicit-any with IAccount and AccountManager types from applesauce-accounts in hooks
- Replace @typescript-eslint/no-explicit-any with unknown type casts in App.tsx for keep-alive subscription
- Fix react-hooks/exhaustive-deps warnings by including all dependencies in useEffect hooks
- Remove unused _settings parameters in useImageCache.ts that were causing no-unused-vars warnings
