Run Black formatter across 83 files and fix 1514 ruff violations: - E722: bare except → typed exceptions (17 fixes) - E711/E712/E721: comparison style fixes with noqa for SQLAlchemy (44 fixes) - F841: unused variable assignments (70 fixes) - F541/F401: f-string and import cleanup (1383 auto-fixes) Remaining 925 errors are all F403/F405 (star imports) — structural, requires converting to explicit imports in a separate effort.
