fix(festa): correct reward field version gate from G1 to G3

Browse Source 
The extra reward fields (Unk5, Unk6, Unk7) in the InfoFesta response
were gated at >= G1, but G1 clients do not expect these 5 extra bytes
per reward entry. This caused the entire packet after the rewards
section to be misaligned, corrupting MaximumFP, leaderboards, and
bonus rates — which broke the festa UI including trial voting.

Wii U disassembly of import_festa_info (0x02C470EC, 1068 bytes)
confirms G3-Z2 reads these fields. G1 binary analysis shows only
8 festa packets (vs 12 in ZZ), and the intermediate/personal prize
systems were not added until G5.2/G7 respectively.
