v3.23.3: the low-counter notice polish

The two buttons under a cntr_low verdict shared the red warning style, and
the notice only ever rendered in the RAM pill: an SCP80 send wrote it into
the hidden RAM container, so the plain-send view showed the verdict text
but offered no way to act on it.

- The counter probe button is amber and the preset jump green (the warning
  text stays red).
- The probe renders the inline throbber the RAM operations use
  (animate-spin, no modal) while it runs; its result replaces it in the
  same box.
- Each pill carries its own notice box (#ram-cntr-low / #sp-cntr-low):
  ramShowCntrLow/ramSyncCounter target the originating view's box and
  clear the other, the SCP80 send passes 'sp' explicitly (it used to rely
  on the keyset-view heuristic), and a new send attempt clears the stale
  verdict (ramClearResults clears both boxes).
- The prebuilt Tailwind output was regenerated (npm run build):
  border-amber-300/-700 and border-emerald-300/-700 were absent from
  style.css (the stale-style trap).

Tests: the button classes, the spinner and the box targeting pinned in
ram.test.js.  846 frontend + 830 Python; sw cache simple-v416.
