fix: align all 212 tests with current API and add CI workflows

Update integration tests to match actual endpoint responses: remove
data wrappers, use snake_case fields, correct HTTP methods (PUT→POST
for directory create), status codes (200→204 for mutations), and
request formats (params→json for 2FA). Fix root-level and unit tests
for DatabaseManager migration, model CRUD patterns, and JWT setup.
Add GitHub Actions and Gitea CI configs with ubuntu-latest + Python 3.13.
