When CURSOR_SHOWING=0 (no physical mouse on Win 11/Server 2022/headless
endpoints), upstream returns Ok(None) → no cursor message ever sent on
the wire → web client / native viewer renders nothing for the cursor.
Patch: load IDC_ARROW so the viewer always receives a valid cursor.
Hash-pinned by IconInfo so it's effectively a one-shot per session.
Required for our MSP use case where a substantial fraction of endpoints
are headless servers (Hyper-V hosts, Win Server 2022 with no console
mouse). Bundled with OnRamp via Install-RustDeskClient binary replace.
