fix(home): split starter fine print, show hints only when actionable (BUG-1041)

TASK-starter-home-polish-20260926:
- D1 today's trend moves to a sub-line under the greeting
  (.starter-greeting-sub), read from the same dailyStarlanguage state the
  warm snapshot seeds; static sentence until ready, hidden without a minute.
- D2 the line under the pills appears only for a resumable case or a
  non-self subject; the first-run and redo sentences are removed.
- BUG-1041 entrySummaryFromResponse read snake_case keys while the
  entry-summary route returns camelCase, so every account parsed as a
  first run; the parser now reads the route's shape (snake_case still ok).
- D3 daily entry icon MoonStar, credits icon Coins; D4 boundary line kept.
- Records: CHANGELOG, DESIGN, VOICE, BUG_HISTORY, PROGRESS, testing list.
