refactor(entrypoint): move route registry into entrypoint context (#200)

- Introduced `NewTestRoute` function to simplify route creation in benchmark tests.
- Replaced direct route validation and starting with error handling using `require.NoError`.
- Updated server retrieval to use `common.ProxyHTTPAddr` for consistency.
- Improved logging for HTTP route addition errors in `AddRoute` method.

* fix(tcp): wrap proxy proto listener before acl

* refactor(entrypoint): propagate errors from route registration and stream serving

* fix(docs): correct swagger and package README
