Fix: Correctly route /openapi.json and /api/* paths in Nginx config

[ThomasRitaine]

Overview

This PR addresses the routing issue described in #1134, where accessing the /api/docs endpoint failed to load the OpenAPI definition due to an incorrect path for fetching /openapi.json. By updating the Nginx configuration, both the /api/* and /openapi.json paths are now correctly routed, ensuring the documentation UI functions as expected.

Changes

• Modified the Nginx configuration to match both /api/* and /openapi.json with a single rule.
• Added a rewrite rule for /api prefixed paths to correctly route API requests without affecting the /openapi.json endpoint.

Impact

• Resolves the documentation UI issue by allowing /api/docs to successfully fetch the OpenAPI definition.
• Simplifies the routing logic in the Nginx configuration, potentially reducing future maintenance efforts.

Testing

• Verified that the documentation UI at /api/docs correctly loads the OpenAPI schema.
• Confirmed that API routes are unaffected by the new Nginx configuration rule.

Closes #1134
