[47] [C#-QUESTPKT.1/2/3 + QUESTREWARD.1] Quest packet/reward serialization bugs

[alseif0x]

• QUESTPKT.1: SMSG_QUERY_QUEST_INFO_RESPONSE omits the ReadyForTranslation bit before flush.
• QUESTPKT.2: QuestRewardsBlock serializes QuestChoiceItem with wrong order/layout (missing 2-bit LootItemType; ItemInstance/Quantity out of order).
• QUESTPKT.3: SMSG_QUEST_GIVER_QUEST_COMPLETE omits the trailing ItemReward (ItemInstance).
• QUESTREWARD.1: reward dialogs feed QuestRewardsBlock with incomplete/unscaled data (raw money; XP/rep/currency/skill/faction/treasure-picker absent or 0).
  C++: Server/Packets/QuestPackets.cpp/h, Entities/Player/Player.cpp (RewardQuest).

Done = contrast Rust vs the cited C++; if it matches, re-anchor the comment to C++ file:line; if it differs, fix behavior to C++. Live + capture-clean. 1 issue = 1 PR.
