Rebase openrvdas_dev onto main v1.0.2

[webbpinner]

main has been released as v1.0.2. Rebase openrvdas_dev onto it, per the branching workflow in CLAUDE.md / RELEASING.md.

v1.0.2 contains #28: template mypy fixes, the pydantic.mypy plugin, and a blocking CI mypy step. After #26, openrvdas_dev has no OpenRVDAS-specific mypy errors left, so after this rebase mypy should pass completely and CI will enforce it.

Expected conflicts (dry-run rebase):

• pyproject.toml: first hit on the very first replayed commit. Keep the OpenRVDAS name/version/description and dependency changes, and take main's [tool.mypy] plugins = ["pydantic.mypy"]. Resolve hunk by hunk, not by taking a whole side.
• The dry run stops at the first conflict, so later ones weren't checked. Likely candidates are the files Fix template mypy errors and make CI mypy blocking #28 touched that also differ on this branch: app/config.py (database_url: str = "" and the cached_data_server_* settings), app/db/session.py (async_sessionmaker) and tests/conftest.py.
• poetry.lock: regenerate after the rebase.

Migration chain: this release has no migration changes. Keep 6e53aa40f2e0 out of this branch (removed in #22) and confirm alembic heads shows d2e3f4a5b6c7 as the only head.

Verify before force-pushing: black / isort / flake8 / mypy all clean, pytest passes, and alembic upgrade head on a fresh SQLite database.

Done: openrvdas_dev has been rebased onto main v1.0.2 and force-pushed (79fe172 → df6251f). It is now 0 behind and 44 ahead of main.

Conflicts: only two, both in pyproject.toml, resolved hunk by hunk:

• Kept the OpenRVDAS name/version/description and dependency changes.
• Added main's [tool.mypy] plugins = ["pydantic.mypy"] without duplicating [tool.pytest.ini_options].

Everything else auto-merged. Compared with the old openrvdas_dev, the only changes are #28's eight files. Template files differ from v1.0.2 only by the intended OpenRVDAS additions (cached_data_server_* settings, get_async_server_api, dependencies). The merge commit from #27 was dropped by the rebase as usual; its content is in 785be3e.

Verification

• black / isort / flake8: pass
• mypy: no issues in 39 files (first fully clean run on this branch; now blocking in CI)
• pytest: 71 passed
• poetry.lock: already consistent (poetry lock made no changes)
• alembic heads: d2e3f4a5b6c7 is the only head; alembic upgrade head on a fresh SQLite database works
• CI on openrvdas_dev after the push: all steps pass (run 35840547149)

Next: #31.
