front(lint): ESLint 9 flat config + angular-eslint 19

- eslint.config.js (flat) : recommended TS + angular-eslint (ts + templates
  a11y), règles selectors app + no-unused-vars (^_ ignoré)
- script lint -> 'eslint .' (+ lint:fix), évite la résolution du builder
  Angular sous pnpm
- fix de la seule violation (variable _ inutilisée dans l'effect catalog)
