Decomp twelve game-state and recycle-shop accessors

Decompile from asm: AddMoneyStored 0x02010758 SetEggSpecies 0x02010794 SetUnkGameState0x13a6 0x020107C4 SetEggHatchTimer 0x020107F4 DecrementEggHatchTimer 0x0201080C GetRecycleItemId 0x02011DF0 RecycleItemHasTradeTypePrizeTicket 0x02011DFC GetRecycleItemBonusOdds 0x02011E18 ClearRecycleShopOffer 0x02011F14 GetGameStateRecycleCount 0x02011F30 GetRankForRecycleShop 0x02011F48 GetRecycleOfferCooldown 0x0201227C Nine of these reach BAG_ITEMS_PTR_MIRROR. Five are the setters matching getters already landed; the other four use offsets past them, so struct bag_items gains four more fields, up to 0x13B4. As with the previous extension they are appended past the end, and the field at 0x13AC is left to align naturally rather than declaring a byte at 0x13AB that nothing reads. AddMoneyStored tail-calls SetMoneyStored, which is still asm; its prototype is provisional. DecrementEggHatchTimer only decrements a non-zero timer, which the target expresses with predicated subne/strneh rather than a branch. The remaining three take a pointer to a pointer to a small struct with fields at 0x0, 0x4 and 0x12. No existing type matches that layout, so it is introduced as struct unk_02011DF0, named for the lowest-addressed function that takes it, with placeholder fields. The bytes between 0x8 and 0x12 are unexamined and left as filler. Every one of the twelve matched on the first candidate. No comments are added to any pmd-sky file. Authored by Claude (Opus 5) under human direction. Confirmed by a matching build: build/pmdsky.us/pmdsky.us.nds: OK. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
