fix(ci): resolve nostr-tools v2 compatibility and VideoModal regressions

- Fix `nostr-tools` v2 compatibility:
  - Update `js/nostr/adapters/nsecAdapter.js` to convert hex private keys to `Uint8Array` before passing to `getPublicKey`.
  - Update `js/nostr/nip46Client.js` to ensure keys are bytes for `getPublicKey`.
  - Update `tests/nostr/nip46Client.test.js` and `tests/nostr-private-key-signer.test.mjs` to use `Uint8Array` for keys.
- Fix `VideoModal` regressions:
  - Add missing delegation methods (`setCommentsVisibility`, `clearComments`, `resetCommentComposer`, `setCommentStatus`, `setCommentComposerState`, `appendComment`, `renderComments`, `setCommentSectionCallbacks`, `hideCommentsDisabledMessage`, `showCommentsDisabledMessage`, `updateCommentCharCount`, `updateCommentSubmitState`) to `js/ui/components/VideoModal.js`.
  - Expose getters for `commentsList`, `commentsComposer`, etc., in `VideoModal.js` to support tests.
  - Implement `setCallbacks` in `js/ui/components/video-modal/commentsController.js` and ensure robust initialization when DOM elements are missing.
  - Fix `open()` and `updateSourceAvailability()` in `VideoModal.js` to correctly re-enable Share, Embed, and Copy Magnet buttons.
- Fix `DeleteModal` tests to comply with linting rules (avoid direct `.style` assignment).
