Hithomelabs/CFTunnels#149: Fix actuator security to allow unauthenticated health/info on management port

- Upgrade ActuatorSecurityConfig to @Order(Ordered.HIGHEST_PRECEDENCE) at class level
  to ensure filter chain is evaluated before auto-configured management security
- Replace string-based securityMatcher with EndpointRequest.toAnyEndpoint() for
  proper Spring Boot actuator endpoint matching
- Add belt-and-suspenders permitAll() for /actuator/health and /actuator/info in
  SecuirtyConfig so health endpoints are accessible even if filter chain ordering fails
- Root cause: SecuirtyConfig catch-all (no securityMatcher) was intercepting actuator
  requests on the separate management port (management.server.port=8081) and
  redirecting to OIDC login before ActuatorSecurityConfig filter chain could apply
