Filter API docs to only show /api endpoints

Add custom OpenAPI schema generation to filter documentation
to only include routes starting with /api/. This keeps the
API docs clean and focused on the actual API endpoints without
cluttering them with web page routes.

The /api/docs will now only show:
- /api/search
- /api/verse-of-the-day
- /api/verse/{book}/{chapter}/{verse}
- /api/verse-range/{book}/{chapter}/{start}/{end}
