[Change] trim redundant comments in issue #483 emission + tests

[Change] _lmd_render_json_list() sort-buffer preamble: drop 3 lines that
         duplicate the ticket + commit-message narrative about the
         pre-fix misorder; keep the load-bearing canonical-reference and
         tab-safety invariant in 4 lines.
[Change] tests/31-json-report.bats test 31: drop the trailing WHAT
         comment above the started_epoch regex — the regex already
         expresses the assertion.
