chore: unify ESLint config and versions to winecode standard

Align the non-@rdlabo ESLint setup to the winecode/app standard, unify
dependency versions across the fleet, and fix resulting violations so
`ng lint` passes.

- rules: selector / component-class-suffix / prefer-on-push and the 8-rule
  off-set aligned to winecode; off-rules not in the standard removed
- versions: eslint ^9.39.4, @eslint/js ^9.39.4, typescript-eslint ^8.61.1,
  angular-eslint 21.4.0
- keep lint green (pre-existing debt fixed as needed)
