v3.3.0: CDN frontend delivery + avatar refresh

Add optional CDN mode that serves JS/CSS from an external CDN instead of
Moodle's filesystem, decoupling frontend updates from plugin upgrades.

- Rollup build bundles all 10 AMD modules into single sola.min.js (224KB)
- Mini AMD loader with shims for core/ajax (fetch) and core/str (pre-loaded i18n)
- Two new admin settings: CDN Base URL + CDN Asset Version (cache busting)
- GitHub Actions workflow auto-deploys to gh-pages on push
- Clearing CDN URL reverts to local AMD files (zero-risk fallback)
- CDN setting strings added to all 46 languages
- Replaced avatar SVGs 02-10 with optimized PNGs (13-22KB each)
