feat(config): support *_MB env vars for upload size limits

- Prefer `*_BYTES` when set, otherwise convert `*_MB` to bytes with overflow guard
- Add coverage for MB-based environment overrides
- Introduce `static/js/upload-popups.js` to lazy-load and cache popup templatesfeat(config): support *_MB env vars for upload size limits
