fix(#5501): clear pending retry state on render invalidation (Codex gate)

Codex re-gate SILENT: a retry whose fetch is invalidated mid-flight (e.g. a
profile switch) left the button stuck as an inert 'Retrying…' with no request in
flight — the stale catch returns before _showSessionListLoadError and the
.finally() bails when the skeleton removed the old button. _invalidateSessionListRenders()
now clears the pending retry markers (retrying, _retryFailedFocus) so the next
repaint shows an actionable idle Retry. Regression test added (fails without the
fix); test harness extracts _invalidateSessionListRenders + declares its render-gen
globals.
