chore: ajoute ruff (lint) et corrige les violations

- Config ruff dans pyproject.toml : règles E/W/F/I/UP/B, whitelist des appels
  d'injection FastAPI (Depends/File/Form/Query) pour B008, B904 ignoré
  (traduction volontaire des exceptions en réponses HTTP)
- Auto-fixes : tri des imports, suppression d'imports inutilisés, annotations
  PEP 604, f-strings sans placeholder, modes open redondants
- Suppression de variables inutilisées (config.reset_setting, parser locataires)

ruff check . : All checks passed ; 61 tests OK
