Subject: [PATCH] fix: resolve final 5 backend test failures
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- script_template.py: add server_default to ALL NOT NULL columns so
  Base.metadata.create_all matches Alembic behavior for raw SQL INSERTs
- test_session_branches_api.py: fork_reason needs 5+ chars ("test" → "testing fork")
- test_scripts.py: engineers CAN create templates (assert 201, not 403)
