Use fixed-width counts in the NetworkId and Unicode packed maps

These three AutoDeltaPackedMap specializations wrote their command count as
int32 but wrote the baseline count, and read both counts, as size_t. Under
ILP32 size_t was 4 bytes so pack and unpack agreed. Under LP64 size_t binds
to the 8-byte uint64 Archive overload, so pack writes 4+8 bytes while unpack
reads 8+8 and leaves the stream misaligned by 4 bytes for every subsequent
key and value.

Switch both counts to int32_t, matching the generic internal_pack/
internal_unpack path and the already-converted PlayerQuestData specialization.
This also keeps the serialized form identical to the 32-bit server, so data
written by either architecture stays readable by the other.
