Improve documentation for configuration properties

- Add missing properties to README configuration example:
  - url, connect-timeout, read-timeout
  - Filter properties (login.submissionPath, login.redirectUrl, token.parameterName)
- Update additional-spring-configuration-metadata.json with all 11 properties
  for better IDE autocomplete support
- Fix README code example to use constructor injection (@requiredargsconstructor)
  instead of field injection (@Autowired)
