Subject: [PATCH] security: fix magnet parameter injection and data loss

- Fix magnet parameter injection vulnerability in `js/magnetShared.js` by ensuring all parameter values are decoded during normalization and re-encoded during URI construction.
- Fix a data loss bug in `normalizeMagnetInput` where parameter values containing `=` were truncated due to `split("=", 2)`.
- Consistently decode all magnet parameter values to ensure a clean internal representation.
- Use `encodeURIComponent` in `buildMagnetUri` to safely reconstruct the magnet URI.
- Update `tests/edit-modal-submit-state.test.mjs` and `tests/video-note-payload.test.mjs` to handle encoded magnet URIs.
