Rudimentary file support

we now have the most basic kind of file support there could be. which is just storing the path to the file. we then provide a link to the file in the frontend, clicking on which reveals the file in your explorer.

we also now have tiny little icons on the entries which indicate the entry type. all icons thanks to https://lucide.dev/

files ofcourse, need a bit more work. right now, you cant really do much except revealing in explorer. i will work on adding copy and paste support for files next, as well as maybe improve the overall performance a bit.
