fix(amo): eliminate all innerHTML to satisfy Firefox AMO linter

Replace li.innerHTML, repoHeader.innerHTML, notificationsList.innerHTML,
and markAllBtn.innerHTML with DOM API construction (createElement,
textContent, replaceChildren, createContextualFragment).

Add getIconSVGElement() to icons.js using createContextualFragment
for safe SVG injection. Add comment_bubble and checkmark SVG icons.
Update manifest-firefox.json with required data_collection_permissions.
