Fix: Access to Swagger UI when login enabled (#5194)

Fixes for /swagger-ui/index.html & /v1/api-docs endpoints not being
accessible when login was enabled.

- `UserAuthenticationFilter.isPublicAuthEndpoint()` had gaps in its
check, missing `/v1/api-docs`
- Refactored `UserAuthenticationFilter` to use
`RequestUriUtils.isPublicAuthEndpoint()` instead of its own incorrect
method

Closes #5125 & #5028
