DRTVWR-418: Use U32 for int (and hex) of HttpStatus in 64-bit too.

Turns out that Monty didn't intend for the int-flavored representation of
HttpStatus to expand to 64 bits even when unsigned long is that wide. So
change the implicit conversion operator, and its uses, to U32 instead. That
produces a consistent toHex() result for both 32-bit and 64-bit builds.
