monad-wireauth: parametrize metrics

[dshulyak]

wireauth will be used for both TCP and UDP and we need separate
metrics , and since we don't support labels we just generate different instances of metrics

[Copilot]

Pull request overview

This pull request parametrizes metrics in the wireauth module to support separate metric instances for TCP and UDP transports. Since the codebase doesn't support metric labels, different instances of metrics are generated with transport-specific prefixes.

Changes:

• Refactored metrics from global constants to a struct-based approach with parameterized metric names
• Introduced a macro to generate transport-specific metric instances (UDP and TCP)
• Updated all API constructors and internal components to accept metric names as a parameter
