fix: dependabot package upgrades (idna, authlib)

Resolves dependabot PRs #595, #596, #597 (idna), #589 (authlib).

- idna: 3.13 -> 3.17 across requirements.txt and uv.lock files
  (bumped past dependabot's 3.15 to latest via uv resolution)
- authlib: 1.6.11 -> 1.6.12 (ContentProcessorWorkflow)
- Regenerated uv.lock for ContentProcessor, ContentProcessorAPI,
  ContentProcessorWorkflow with --upgrade-package flags
- Side effects from re-resolution:
  - github-copilot-sdk: 0.2.2 -> 0.3.0 (transitive in CP)
  - urllib3 lock entry synced to 2.7.0 (matches pyproject) in CPAPI
  - jsonschema deps added to CPAPI lock (matches pyproject)
