refactor: Port the main window to a .ui file

some stuff still needs to be done in the c++ side because qt designer is dumb >:(

the instance toolbar icon and instance name buttons are still added manually inside MainWindow.cpp

looks almost identical, with some minor tweaks:
- the instance toolbar is now a WideBar, so you can customize what actions you want :D
- the instance toolbar buttons are now fullwidth
- the close window button is now at the end of the file menu
- the help menu has some layout changes

this also fixes some stuff:
- menus not having tooltips
- the top toolbar not connecting to the title bar in kde
- the instance toolbar separators looking weird after you move the toolbar
