📄 Description

Describe your changes

Signal and Management servers previously hard‑coded a pprof listener on localhost:6060, which caused port conflicts when multiple services ran in the same namespace (ie; in the same pod or as a NixOS service). This PR refactors both to use the same pprof.go helper pattern already present in Client/Relay.

Does this change build semantics though? To test it, I ran it with -tags pprof. If it does, it shouldn't be a huge change to just slap what pprof.go does directly into the relevant functions.

Checklist

Is it a bug fix
Is a typo/documentation fix
Is a feature enhancement
It is a refactor

Documentation

Select exactly one:

I added/updated documentation for this change
Documentation is not needed for this change (explain why)

The behavior is consistent with existing Client/Relay profiling logic, so no new user‑facing configuration is introduced beyond the existing NB_PPROF_ADDR.

Summary by CodeRabbit

Refactor
- Centralized profiling support into a shared utility and adjusted initialization across components.
- Removed automatic local profiling server startup in some services; profiling is now opt-in.
Chores
- Introduced a build-time toggle to exclude profiling when not needed.
- Changed the default profiling address from localhost:6969 to localhost:6060.
