chore: pass the allocator as an argument more often
...
As of right now, I think the only cases where I shouldn't explicitly pass an allocator
are in read/write functions and deinits

fix: resolve use-afer-free in backup.zig
...
This worked fine on stage1, and works fine in debug in stage3.
However, stage3 ReleaseSafe would panic due to what I assume must
have been an undefined behaviour optimization.
While I'm happy that I was quickly made aware of the issue thanks to
the safety checks in ReleaseSafe I do wish that this issue showed itself
in Debug, since I *am* using the GPA
