fix: replace all innerHTML assignments with safeHTML for AMO review

Browse Source 
Replaced all 31 innerHTML assignments across popup.js (12),
options.js (17), and content.js (3) to pass Mozilla AMO linter.

Each file gets a safeHTML(el, html) helper:
- popup.js/options.js: DOMParser-based (extension page context)
- content.js: <template> element pattern (page world context)

Empty innerHTML clears replaced with el.replaceChildren().
innerHTML += replaced with createElement + safeHTML + appendChild.

All event listener bindings after HTML rebuilds remain functional
since safeHTML uses replaceChildren() which populates DOM
synchronously before querySelectorAll + addEventListener calls.
