chore(a3p-integration): Improve log output (#10485)

## Description
Extracted from #10165 and best reviewed by commit.
* Include relevant variable details (e.g., block height).
* Omit output that doesn't convey new information "done", "reading", etc.).
* Provide a common logging prefix for subtasks, inlining functions where relevant.
* Remove endo/init/legacy.js from z:acceptance ava config to eliminate noisy `Object <[Object: null prototype] {}>` output.
* Introduce a `logRecord` helper to concisely log possibly-remotable-bearing records and/or record entries.
