fix(#1471 followup): re-inject Customizer/Search/Favorites mirrors when More sheet opens (#1476)

**Problem:** Operator reports Customizer link missing from the
bottom-nav More sheet on prod (v3.8.2). bottom-nav.js builds the sheet
lazily on first More-click. mobile-page-actions.js calls
addMissingMoreSheetItems() at DOMContentLoaded + retries 10×500ms — so
if operator doesn't tap More within 5s of page load, mirrors never
appear.

**Root cause:** The earlier polish round (commit 70a570c6 within #1471)
dropped the click-listener that re-attempted injection. Init-time retry
alone isn't enough; bottom-nav builds the sheet ON DEMAND.

**Fix:** Re-add the catch-all click delegate that fires
addMissingMoreSheetItems on any More button click (with
belt-and-suspenders 50ms + 250ms timeouts to handle slow builds).

Hot-deploy candidate (JS-only).
