Emit Events for All State Changes

[Mkalbani]

Description

Several state-changing functions do not emit events, making off-chain indexing and debugging difficult.

Expected Behavior

Every quest creation, update, completion, and cancellation should emit a corresponding event.

Proposed Events

event QuestCreated(uint indexed questId, address indexed creator);
event QuestCompleted(uint indexed questId, address indexed player);
event QuestCancelled(uint indexed questId);
event QuestUpdated(uint indexed questId);

Acceptance Criteria

• All state changes have corresponding events
• Events include indexed fields for efficient filtering
• Tests assert events are emitted correctly
