Viktor Petersson 133ec78ff0 refactor(packaging): adopt src/ layout with split server/viewer packages (#2817)
* refactor(packaging): adopt src/ layout with split server/viewer packages

Move all Python source under src/ following modern packaging conventions.
Server, viewer, host-agent, and shared common code now live as four
top-level packages with clear excision boundaries — anthias_viewer can
be removed wholesale when the rewrite-out-of-Python lands without
touching the server.

  src/anthias_common/         shared: errors, utils, internal_auth, device_helper
  src/anthias_server/         Django app, REST API, Celery tasks, manage.py
    lib/                      server-only: auth, backup_helper, diagnostics, github, telemetry
  src/anthias_viewer/         player runtime (was viewer/)
  src/anthias_host_agent/     systemd-driven host shim (was host_agent.py)
  tools/raspberry_pi_imager/  moved from repo root
  tests/conftest.py           moved from repo root

pyproject.toml gets [build-system], setuptools src/ discovery, and an
anthias-manage console script. Django AppConfigs keep label='anthias_app'
and label='api' so existing migration dependency tuples don't move.
BASE_DIR computed from parents[3] to keep templates/static at repo root.
mypy_path set to ["src", "stubs"] with explicit_package_bases.

Dockerfile templates set PYTHONPATH=/usr/src/app/src; bin/start_*.sh
and CI workflows use python -m anthias_server.manage / python -m
anthias_viewer instead of bare ./manage.py and python -m viewer.
Ansible host-agent unit invokes python -m anthias_host_agent.

Verified end-to-end in the docker test container:
  - 430 unit tests pass (matches baseline)
  - 7 integration tests pass, 5 skipped (matches baseline)
  - ruff, mypy clean

* style: ruff format the new src/ tree

The longer post-rename module paths (anthias_common.internal_auth vs
lib.internal_auth, etc.) pushed several import lines past 79 chars, so
ruff format had to wrap them. Apply that formatting and split the one
multi-import in anthias_viewer/__init__.py into per-symbol lines so the
existing # noqa: E402 sits on the `from` line where ruff expects it,
without needing a re-anchor when format wraps the parens.

* chore: realign sonar + gitignore comment to src/ layout

sonar-project.properties still pointed at the pre-refactor top-level
packages (anthias_app, anthias_django, api, lib, viewer, ...) and
their old per-file coverage.exclusions paths, which would have
produced empty Sonar runs and stale exclusions. Collapse sources to
`src` and rewrite the exclusions to the new src/anthias_*/ paths.

Also fix the stale path reference in .gitignore's comment for the
test DB (now src/anthias_server/django_project/settings.py).

* chore: gitignore .claude/ and untrack the lock file I just leaked

Previous commit accidentally pulled in .claude/scheduled_tasks.lock
because .claude was in .dockerignore but not .gitignore. Add the
pattern to .gitignore and drop the file from the index.

* chore(dockerignore): exclude pytest cache, __pycache__ dirs, and the local test DB

Three entries that were missing relative to the new src/ layout:

- .anthias-test.db (and -journal/-wal/-shm siblings) — created at the
  repo root by src/anthias_server/django_project/settings.py when a
  developer runs the host pytest suite. Without this exclude, the
  next docker build COPY . bakes the file into /usr/src/app/.
- **/__pycache__ — *.py[co] only matched the .pyc/.pyo files, leaving
  the empty cache directories to ship.
- .pytest_cache — host-side, regenerable.

* fix(urls): preserve 'anthias_app' URL namespace, not just the app label

Copilot caught that the import-rewrite swept up the URL namespace too:
app_name in src/anthias_server/app/urls.py changed from 'anthias_app'
to 'anthias_server.app', which leaves templates/login.html's
{% url 'anthias_app:login' %} pointing at a namespace that no longer
exists — NoReverseMatch at render time when an unauthenticated request
hits the login page.

The namespace is the same kind of stable user-facing identifier as the
AppConfig label (which we already kept as 'anthias_app'). Restore it,
and revert the two reverse() callers in lib/auth.py and app/views.py
that the rewrite changed in lockstep.

* fix(ci): update --confcutdir to the new tools/raspberry_pi_imager path

Copilot caught that the earlier sweep missed --confcutdir=raspberry_pi_imager
(no trailing slash) — replace_all of "raspberry_pi_imager/" only matched
path-with-slash forms. Without confcutdir, pytest walks back up looking
for conftests and discovers the repo-root tests/conftest.py, which
applies the Anthias-specific Django/Redis stubs to the rpi-imager test
run on the website-deploy workflow.
