Advertise the REST endpoint during Consul registration

[mbuckton]

What changed

• add the running REST endpoint to the existing Consul metadata
• use the REST manager's configured port
• retain explicit REST bind addresses
• replace 0.0.0.0, ::, and wildcard-only address lists with the local interface selected by the OS route to Consul
• format IPv6 endpoints correctly
• skip Consul service registration when the REST API is disabled

Why

Consul must advertise and health-check a reachable MapsMessaging address. A wildcard bind address is valid for listening but cannot be used by Consul clients.

For example, when Consul is at 10.140.62.193:8500, route-based selection advertises the Ethernet address 10.140.62.146, rather than an APIPA or Hyper-V adapter address.

Companion change

Configuration library PR: Maps-Messaging/configuration_library#47

Validation

Added focused tests for configured addresses, IPv4 wildcard replacement, wildcard lists, IPv6 formatting, and invalid ports. The companion library tests cover route selection and invalid Consul URLs. git diff --check passes.

The Maven test could not run in the available environment because the MapsMessaging and Maven repositories are not reachable and no dependency cache is available.
