wrappers: flip BigEndian → LittleEndian on PackShort/PackInt/PackLong

Browse Source 
LE everywhere — native byte order on x86 and ARM (no byte-swap cost).
Aligned with LP-023 ZAP cutover and the zapcodec internal LE encoders.

Test fixtures regenerated for LE byte order. Pre-existing BE-encoded
on-disk bytes are NOT readable by this version — caller-side migration
required (or fresh-bootstrap).
