Walkthrough

This pull request introduces a filtered parameter to address retrieval methods across the address manager and network connection interfaces, enabling callers to optionally disable filtering of "terrible" addresses. It adds ASMap health check functionality that validates ASMap effectiveness by collecting and analyzing address-to-ASN mappings during startup. The PR also relocates the GetServicesNames helper function from rpc/util to rpc/net to consolidate service-related RPC utilities. Additional changes include RPC documentation refinements, new include directives, and test cases validating unfiltered address retrieval and ASMap health check behavior.

🎯 3 (Moderate) | ⏱️ ~25 minutes

🚥 Pre-merge checks | ✅ 1 | ❌ 2

❌ Failed checks (1 warning, 1 inconclusive)

Check name	Status	Explanation	Resolution
Docstring Coverage	⚠️ Warning	Docstring coverage is 11.11% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.
Description check	❓ Inconclusive	The description 'Backports' is very minimal and generic, using a non-descriptive term that conveys no meaningful information about which specific changes or features are being backported or what their purposes are.	Expand the description to identify key changes being backported, such as ASMap health checks, address filtering logic, and RPC refactoring, to give reviewers context.

✅ Passed checks (1 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title clearly references specific Bitcoin upstream PRs (#28136, 27581, 18919, 25634, 25284, 27829) being backported, which matches the diverse changes across address management, ASMap health checks, RPC refactoring, and test additions.
