Document the config API contract and error codes

Document the config API

Description

The config endpoints lack a single reference for their request/response shapes and error codes, slowing integrators. This issue documents them.

Requirements and context

• Repository scope: StableRoute-Org/Stableroute-backend only.
• Add docs/config.md covering each config route, its params, response shape, and error codes.
• Cross-reference the handler; keep it accurate to the code.
• Include a request/response example per route.

Suggested execution

• Fork the repo and create a branch
• git checkout -b docs/config-01-api
• Implement changes
  • Write code in: the relevant module.
  • Write comprehensive tests in: cover the new behaviour and edge cases.
• Test and commit

Test and commit

• Run npm run lint, npm test, and npm run build.
• Cover edge cases: n/a — verify each documented route against source.
• Include the full test output in the PR description.
