v3.2.121 — Updates refresh the remote agent package

After updating to 3.2.121, click Update Now once more. An update runs the update script that's already installed, so the update to 3.2.121 is done by the 3.2.120 script, which doesn't refresh the agent package. The second run uses the 3.2.121 script and applies it. If you prefer, copy agent/ from this release into /opt/urbackup-gui/agent/ by hand instead.

You only need this if you install agents on remote hosts. Nothing else changed.

Fixed

• Updates never refreshed the remote agent package. "Install agent" over SSH and the one-time install command package /opt/urbackup-gui/agent and send it to the remote host, but the update script never synced that folder. Updated installs kept shipping the agent they were first installed with. On 3.2.120 that agent failed to build (tsc: not found) and set up no certificate, which the 3.2.120 backend requires before it will talk to a remote agent. Updates now sync agent/, and remove files the release no longer ships.
• Updates left VERSION behind. Only version.json was copied, so VERSION kept whichever version was first installed. Both are copied now.
