Pull Request Overview

This PR removes all usages of the legacy GraphClient, replaces graph-based event fetching with the new Intmax event server API, and updates configuration accordingly.

• Add a new event_server_url configuration option and remove graph_url/timeout.
• Remove all GraphClient imports and related helper functions (sync, health checks, sleeps).
• Introduce get_deposit_events in external_api::intmax::event to fetch deposited events.

• Consider adding tests for error cases (e.g., invalid JSON or server errors) in get_deposit_events to verify that error paths are handled correctly.
