feat: Enable system notifications on cloud (#7277)

Re-enables the system notification popup for cloud distribution,
allowing cloud devs to notify cloud users about new features and updates
without requiring a new release.

Cloud now fetches release notes from the "cloud" project (instead of
"comfyui") and uses the `cloud_version` field for version comparison.
Since cloud versions are git hashes rather than semver, a helper handles
both formats gracefully.

The "What's New" popup is enabled for cloud, while the update toast and
red dot indicator remain desktop-only since cloud auto-updates and
doesn't require user action.

You can test this by doing `pnpm dev:cloud` and you will see a
notification I added (for testing):
