Minor bug fixes

[VirxEC]

• Objects created using $state are proxied for interior mutability reactivity but this broke mutator presets. Interior mutability is not needed, the object is only ever updated as a whole, so using $state.raw is a valid fix. (With proxied objects, === is always false which lead to an infinite update loop.)
• The suggested path for the botpack would still have /bots at the end. Appending bots to the end of the path is now handled in Go through the proper API, so its now /bots or \bots depending on the platform.
• I think a recent update to wails changed how events work, event.data used to be a list of objects if the same event was fired a lot in a short period of time. event.data isn't a list anymore, it contains the information from only 1 event. This broke the download & extract progress bars which has been fixed.
