Merge pull request 'fix(api): widen alembic_version.version_num in migration 001 (CAR-1302)' (#289) from barcode-betty/car-1303-widen-alembic-via-migration into dev

fix(api): widen alembic_version.version_num in migration 001 (CAR-1302)

Rebased onto current dev head ad18a43b5 per CAR-1365. Drops 71e3b81 (already in dev via #281). Resolves ci.yml conflict by keeping dev's CAR-1316/1318 fixed version. Self-merge per SDLC Phase 1 (CI green on run #3470).
