fix spacedrive:// custom protocol on Windows

[oscartbeaumont]

Changes:

• Hopefully fixes ERR_UNKNOWN_URL_SCHEME - Windows #520
• Move the handle_custom_uri function to use primitives from the http crate instead of my old janky tuple. Required for steaming and is probably how I should have built this system originally.
• Streaming the response for files using the protocol. This is so we don't need to load the whole thing into memory.
  • Streaming the response for any arbitrary file format requires chunked encoding. Support chunked encoding is hard so this PR only deals with chunking of video files which use a whole different system composed of multiple HTTP requests for the same resource which is way easier to implement.
• Add a new part to the protocol for loading in files (spacedrive://file/{library_id}/{location_id}/{filepath_id})
• LRU cache for video file metadata in spacedrive://file/* proto
• JS helpers for generating the URL on web, desktop Unix and desktop Windows.
• Replace enums with string unions in Typescript. Enum's have many footguns!
• To fix Linux I had to upgrade Tauri. This then necessitated updating both rspc and PCR for it all to work.

@jamiepine this works and is ready for use.

I would appreciate it if @brxken128 could give it a shot on Linux because I am concerned about if video files will work on Linux. I don't think it will stream video files on Linux and as far as I'm aware this is a Tauri limitation. It should instead, I am hoping, just load it all into memory and sends it to the webview. We could build a custom protocol to work around this limitation but that is a future concern.

@james-elicx I would appreciate a test of preview media loading on Windows (although don't feel obligated to). I was unable to use the Rust code snippet you sent as it was causing issues on macOS. The system I designed converts the spacedrive:// (Linux/macOS style) to http://spacedrive.localhost (Windows style) and then the code works on that. This choice was because the URL parser in the http crate expects a full URL. Thanks for reporting the Windows issue!

Right now I added a button to the right-click menu on an explorer item to test this feature. It does a full webview redirect which is something that @jamiepine is going to improve when the UI he is working on is ready.

This PR should be working now and it would be great if @brxken128 could check if video playback is working on Linux when he gets a minute. I would also appreciate a Windows test by @james-elicx if you can find the time.

Looks like the protocol and thumbnails are working correctly on Windows now! I appreciate all the work you've done to fix this :)

I've already spoken to @oscartbeaumont about this, but on Linux (Gentoo) it's a mixed bag. Thumbnails work, and opening images work, but video playback does not. It could either be a Tauri thing, or something to do with our protocol - I'm not too sure here.

We're making progress though as only thumbnails worked before.
