[SILO-964] chore: route all /auth/o/token calls to internal api base url (#65)

* [MCP-1] feat: build check workflow (#15)

* fix: added build check workflow

* chore: typo fixes

* release: v0.1.5

* chore: use uv.lock for reproducible Docker builds

- Update Dockerfile to use uv sync --frozen instead of uv pip install
- Ensures exact dependency versions from lock file are used

* fix: add internal URL support for server-to-server calls

- Add plane_internal_base_url for server-to-server calls (token exchange, API verification)
- Authorization endpoint uses external URL (user's browser)
- Token endpoint uses internal URL (optimized for internal network)
- Add Redis storage logging and fix port type casting
- Falls back to external URL if internal not configured
