refactor: extract Discord.js code from shared services into bot layer

Move terminal.service.ts and prune.service.ts entirely to bot/modules/
since they are Discord-specific. Split lootdrop.service.ts: pure logic
(activity tracking, DB ops, claim) stays in shared/, Discord operations
(message sending, channel interactions) move to bot/modules/economy/
lootdrop.handler.ts. Move effect registry/handlers/types from bot/ to
shared/modules/inventory/ since they contain no Discord.js imports and
are needed by inventory.service.ts in shared.
