Fix paginator counter on x86-32

Fix paginator counter on x86-32

Atomic operations with 64 bit values must be aligned for 64-bit on x86-32.

According to the spec:

"The first word in a global variable or in an allocated struct or slice can be relied upon to be 64-bit aligned."

The above wasn't enough for the `paginationPageCount` on `SiteInfo`, maybe due to how `SiteInfo` is embedded.

This commit adds a 4 byte padding before the `uint64` that creates the correct alignment.

Fixes #2415
