refactor(logs): collapse no-op ternary, drop speculative export, fix stale comment (F8,F9,F10)

F8: formatJSONLogs plain-text fallback — both arms of `withTimestamps ? rawText
    : text` yield rawText (text === rawText when !withTimestamps), so use rawText.
F9: controllerLogsController comment referenced the old 'Live logs' label removed
    by F7 — update it to 'Auto-refresh logs'.
F10: stripHeadersFunc has no external importers — drop the speculative export.
