fix a few asan reported leaks on exit of hyprland

[gulafaran]

Describe your PR, what does it fix/add?

a few of the leaks are mostly unimportant since the OS will reclaim the memory anways, but it reduces the asan spam if one builds with it atleast.

Is there anything you want to mention? (unchecked code, possible bugs, found problems, breaking compatibility, etc.)

the changes could use some testing and reviewing so i didnt miss anything obvious, perhaps some weird combination of HW and situation will cause some use after free?

dunno why this is a problem but sure I guess

i knew i missed something obvious, im on a laptop and went into the closet digging for some dusty old logitech usb keyboard. hottplugging its gonna double free because its not set to nullptr here
