refactor(channelserver): split repo_guild.go into domain-focused files

The 1004-line monolith covered 11 game subsystems across 62 methods.
Split into 7 files by domain (RP, posts, alliances, adventures, hunts,
cooking) while keeping core CRUD/membership/scouts in the original.
Same package, receiver, and interface — no behavior changes.
