docs: align upload guide with code behavior and fix ci dependencies

- Update `content/docs/guides/upload-content.md` to enforce HTTPS for external URLs and clarify file validation.
- Fix `SignerManager.js` permission request logic (pass extension instance).
- Fix `NostrClient` signer registration and hydration.
- Install `jsdom` to resolve `ERR_MODULE_NOT_FOUND` in unit tests.
- Patch `tests/nostr-private-key-signer.test.mjs` to handle mocked `nostr-tools` environment.
- Verify changes with `tests/services/s3Service.test.mjs`, `tests/ui/uploadModal-integration.test.mjs`, and `tests/video-note-payload.test.mjs`.
