chore: adopt the NAPALM driver standard

- CI moves to .gitea/workflows/ci.yml and calls the shared driver workflow
  of NAPALM/driver-standard; napalm-device-types and napalm-linux come from
  git until napalm-linux 0.15.0 is on PyPI.
- requires-python >=3.10 (napalm-device-types needs it), SPDX license
  string, setuptools>=77, LICENSE file, py.typed, links to git.netork.io.
- Dependencies: napalm-device-types>=4.22.0, napalm-linux>=0.15.0,
  napalm>=4.0 (tested at 4.0.0); dev extra with pytest, pytest-cov, mypy
  and ruff.
- mypy strict for the whole package, no exempt module: _omv_read is
  annotated as returning list[dict[str, Any]] (types only).
- Coverage floor 15 % (measured 15.89 %); the four long getters and the
  complexity of get_disks are recorded in the quality baseline.
- README (what it is, how it connects, the getters, what it does not do)
  and CHANGELOG are new.
- The committed egg-info and __pycache__ files are untracked; .gitignore
  from the template keeps them, .venv and build output out.
