fix: merge alembic migration heads

Add a no-op Alembic merge revision for 0014_add_profile_resolver_fields and 2026_06_01_add_workspaces so alembic upgrade head resolves a single head during API startup.

Quality gates: alembic heads returns 86cec91fdb00 (head); py_compile and ruff passed on merge revision; fresh review found no blockers.
