Clipboard content leaks to remote computer

[lucentwolf]

Bug Description

Irritating & posing leak-risks:

• A connects to B
• A performs a clipboard-copy (ctrl-c) outside Rustdesk (e.g. in editor)
• B performs a clipboard-paste (ctrl-v) and receives A's clipboard content.

Possibly linked to #7321

I consider this a very high risk since many password managers use clipboards & I don't like Rustdesk to leak it to computers/people I connect to

How to Reproduce

see bug description

Expected Behavior

A clipboard paste should only be using the local computer's clipboard content; that is

• A connects to B
• A performs ctrl-c outside Rustdesk
• If A performs ctrl-v in Rustdesk; A's clipboard content is used (on B's computer via Rustdesk)
• If B performs ctrl-v, B's clipboard content is used (on B's computer)
