feat: add GameEventLogs collection and event emission infrastructure

- New game-event-logs collection with timestamp, type, message, actor,
  structure, targetCollection/targetId, and data (JSON) fields
- EventTypes constants registry for modular event category management
- emitGameEvent() utility for emitting events from server actions and hooks
- Register collection in Payload config
- Document event log system architecture in AGENTS.md

+## Event Log System
+
+`src/collections/game/GameEventLogs.ts` — append-only `game-event-logs` collection.
+
+- **Schema**: `timestamp`, `type` (text/indexed), `message` (human-readable), `actor` (→ users), `structure` (→ game-structures), `targetCollection`/`targetId` (polymorphic ref), `data` (JSON blob).
+- **Emit**: `emitGameEvent(payload, { type, message, actor?, structure?, targetCollection?, targetId?, data? })` in `src/utils/event-log/emit.ts`.
+- **Types**: `EventTypes` constants in `src/utils/event-log/eventTypes.ts` — add new event categories there without touching the collection.
+- **Wiring**: Server actions in `actions.ts` emit events after successful mutations. `GameStructures` afterChange hook catches admin-panel storage edits. `Structures` beforeChange hook emits `structure:resize`.
+- **UI**: `EventLedger` component (`src/components/frontend/storage/EventLedger.tsx`) queries the REST API for a given `structureId` and renders a scrollable feed. Integrated in `StructureStorageView`.
