Ryan Malloy 4781f4d276 panel: trigger initial loadList from discover, prefer loaded entries ...

Two bugs surfaced when smoke-testing against a real OmniPro II:

1. Empty list after page load. _discoverViaList ran fire-and-forget;
   connectedCallback then synchronously checked _entryId (still null
   because await hadn't resolved) and skipped _loadList. The panel
   rendered "No programs match the current filters" forever — until
   the next 5-second poll tick, which never fires because
   _startRefreshTimer was also gated on the same null check.

   Fix: have _discoverViaList itself trigger _loadList and
   _startRefreshTimer after _entryId lands. The connectedCallback /
   updated paths can stay gated on _entryId; the discover path now
   takes ownership of "do the initial load too."

2. Dev installs with both a working entry and a setup_retry entry
   (mock container down, real panel up) had the panel pick the
   setup_retry one first and surface "panel not configured" on every
   call. Fix: prefer entries with state === "loaded" in the discover
   step, falling back to first entry only when none are loaded.

Also: screenshot.py drops the seed-via-WS step (was unsafe — would
write Programs to whatever entry is loaded, including real panels).
Updates the in-page click helpers to walk the shadow DOM recursively
instead of hardcoding HA's host-element path, so detail/editor
screenshots work on the actual depth-8 element location.

Smoke test against real panel: 154 programs render correctly with
structured English, BEDTIME / OPEN BIG GAR / Zone 133 events all
decoded, B. GAR MAN DOOR [SECURE] live-state badge visible.
Detail panel + editor mode both function end-to-end.
