Extract palace.opds into a uv workspace package

Stacked on the palace-util extraction. Move palace.manager.opds into a
new workspace package at packages/palace-opds/ (namespace palace.opds)
and retarget all callers. The OPDS model tree is generic and reusable
across Palace projects; making it a standalone workspace member lets us
publish it independently without dragging in palace-manager.

palace-opds depends on palace-util for the three small cross-cutting
symbols the models need (PalaceValueError, utc_now/to_utc, LoggerMixin).

Callers rewritten (palace.manager.opds.* → palace.opds.*):
- 17 source files across palace.manager.{api, celery, data_layer, feed,
  integration, sqlalchemy}.
- 15 test files across tests/manager/**.

Moved tests:
- tests/manager/opds/** → packages/palace-opds/tests/opds/**. The 5
  tests that only use OPDS2FilesFixture / OPDS2WithODLFilesFixture as
  type annotations now import them under TYPE_CHECKING so the package
  tests don't need tests.fixtures.files at import time; pytest still
  injects the fixtures at runtime via the root-conftest plugin.
- tests/manager/opds/types/test_language.py: replace LogLevel.warning
  with stdlib logging.WARNING so the test has no palace.manager import.

Tooling:
- pyproject.toml: palace-opds added to [project.dependencies],
  workspace members, mypy files/mypy_path, coverage source, pytest
  testpaths. tests-mypy override picks up "opds.*".
- docker/Dockerfile, docker/Dockerfile.baseimage: copy
  packages/palace-opds/pyproject.toml in the cache layer alongside
  palace-util.
- README.md, CLAUDE.md: workspace section extended with palace-opds.
