block remote input isn't blocking anything

**Describe the bug**
A clear and concise description of what the bug is. Ideally with a screenshot if applicable.

when testing out the latest build on a surface pro (client) from my desktop (server), i tested out the "block remote input" feature. i was still able to control keyboard/mouse on the client. is this suppose to block input on client's computer?

**To Reproduce**
Steps to reproduce the behavior:
On server computer, while connected to a client, click on "Block Remote Input"

**Remotely Version**
Server (can be found on about page): 2024.02.23.1927

**Expected Behavior**
if Block Remote Input is enabled, client should not be able to use keyboard/mouse until server is disconnected.

**Desktop (please complete the following information):**
- OS: [e.g. iOS] Windows 11 Pro
- Browser [e.g. chrome, safari] Edge
- Version [e.g. 22] Version 122.0.2365.80 (Official build) (64-bit)

- [ X ] I am running Remotely in Docker and not on my QNAP, Synology, or Internet Connected Toaster

No source files, tests, or code entry points are named in the issue. Start by reproducing the server/client flow on Windows with the reported version, then trace the Block Remote Input action and client-side keyboard and mouse handling. Done means enabling the option prevents client input until the server disconnects.
