feat(library): liste « À regarder plus tard » (watch later)

Nouvelle liste dans la section Vous de la barre latérale, avec un bouton
horloge a cote du coeur sur toutes les cartes (accueil, themes, provider-
themes, recherche).

- db : les 4 fonctions de listes (like/unlike/isLiked/list) prennent un
  paramètre `tag` — la table `tags` sert déjà de mot-clés génériques, donc
  zéro migration.
- api : les 4 routes likes sont générées par registerVideoTagRoutes(prefix,
  tagName) ; /api/user/watch-later = même fabrique, même enrichissement
  yt-dlp, même middleware cookie-aware. Entrée OpenAPI ajoutée.
- front : LikesService prend un VideoTag, like-button un @Input() list
  (icône horloge, ambre quand enregistré, libellés a11y dédiés) — un seul
  composant pour les deux boutons, pas de copie.
- cartes de recherche : la grille partagée n'avait AUCUN bouton ; cœur +
  horloge ajoutés, masqués sur les lives et cartes chaîne (coin bas-gauche
  déjà occupé par le compteur de spectateurs / pas des vidéos).
- route /library/watch-later = LikedComponent via data.list (titre, icône,
  placeholder et état vide pilotés par la route), clés nav.watchLater FR/EN.

Tests : npm run test:api 41/41 (nouveau test watch-later : ajout, statut,
indépendance vis-à-vis des likes, liste, retrait, 400, 401) + 21 autres
suites vertes. Build OK, instance locale 4200 rebuildée. Sondage Playwright
desktop+mobile : 12/14 (2 faux positifs du sondage : accordéon replié sur
une route hors /library, 3×401 console pendant la phase déconnectée).
