test: A32 phase 2a — library 10/10 + 2 routes fantômes supprimées (v7.12.0)

- tests/test_smoke_uncovered.py : +6 tests pour library.py (1/10 → 8 routes
  couvertes) : les 5 listes en boucle (recents/favorites/published/private/
  workspace → 200 + items), /private avec page seedée retrouvée, /children/{id}
  avec parent/enfant seedés, /repository vide ET clé (string, aucun réseau),
  non-régression 404 sur les routes supprimées.
- DÉCOUVERTE (les smokes l'ont prouvé) : `/api/library/local-workspace-children`
  renvoyait un 500 systématique (test vert → ASGI double response.start) et
  `/api/library/local-workspace` 500 dès qu'un workspace existe — les deux
  lisaient `local_workspace_items`, table AUCUNEMENT créée dans le codebase
  (0 CREATE TABLE) et sans 1 seule référence front. Supprimés avec
  `library._format_size` devenu mort (la copie de dashboard.py est inchangée).
  `local_workspace_items` : 0 occurrence restante dans app/.
- helper `_seed_page` minimal (workspace NOT NULL inclus) + nettoyage en
  finally (pas de pollution des autres tests).

suite **1053/1053** (229 s) · `ruff check app tests` OK · docs à jour
restent phase 2b : api.py 3/23, dashboard.py 17/63, api_v2.py 50/115
