fix(enrollment): filter Docker bridge IPs and add report_interface/report_ip config
- identity.rs: filter 172.16.0.0/12 (Docker bridge) and 169.254.0.0/16 (link-local) from get_ip_addresses() auto-detection - identity.rs: add is_container_bridge(), is_link_local(), get_ip_for_interface(), get_primary_ip() functions - client.rs: add report_interface/report_ip fields to EnrollmentClient, new with_ip_overrides() constructor, register() uses get_primary_ip() - loader.rs: add report_interface/report_ip to EnrollmentConfig - mod.rs: wire config overrides through to EnrollmentClient - config.yaml.example: document new report_interface/report_ip options - Tests: add 18 new bridge filtering/IP override tests, fix Docker container compatibility in existing tests
