fix: restore Swagger UI on api-docs page

- Change Vite proxy pattern from /api to /api/ so /api-docs client
  route is not captured and proxied to the backend
- Fix SwaggerUIBundle init: remove empty presets/layout overrides that
  crashed the internal persistConfigs function
- Use correct CSS import (swagger-ui.css instead of index.css)
- Add requestInterceptor to auto-attach JWT token to Try-it-out calls
- Add swagger-ui-bundle to optimizeDeps.include for reliable loading
- Remove unused swagger-ui-dist.d.ts type declarations
