## Description
I have tried to build ente server using the source and have found
various bugs that in a 64bit system would not pose an issue but when ran
on 32bit architecture would result in errors. After the fixes, Ente
works beautifully.
## Why bother merging?
I understand that Ente does not support 32bit architectures by nature
and hence there would be no point in merging this PR and solving these
issues but I have put this PR out there in hopes that it helps others
run Ente on their own desired architecture.
## Changes Description
1. `billing.go` - `storage` variables are not properly typed as int64
despite them being able to hold more than the 32bit integer limit. On a
32bit system, this will lead to an integer overflow (especially with the
default 5GB value). Typing them appropriately as an int64 will resolve
this bug and have no impacts on a 64bit execution.
2. `rate_limit.go` - The code as is will result in an unaligned 64bit
atomic operation ([read
more](https://blog.openziti.io/my-pi-day-journey-with-go-64-bit-alignment)).
In short, the fields were ordered in a way that `count` would start at
the middle of an 8-byte block which is not permitted. Aligning it by
reordering it does not affect the functional aspect but in terms of
golang's memory management, the int64 fields are now properly at an
8-byte boundary, fixing the issue.
## Other 32bit changes
To other open source tinkerers out there, if you wish to use Ente on a
32bit architecture, the dependencies will also need to be recompiled and
rebuilt as they do not have openly available docker images for arm32.
