refactor: consolidate config types and remove file-based config

Tickets: #2, #3

- Remove duplicate type definitions from shared/lib/config.ts
- Import types from schema files (game-settings.ts, guild-settings.ts)
- Add GuildConfig interface to guild-settings.ts schema
- Rename ModerationConfig to ModerationCaseConfig in moderation.service.ts
- Delete shared/config/config.json and shared/scripts/migrate-config-to-db.ts
- Update settings API to use gameSettingsService exclusively
- Return DB format (strings) from API instead of runtime BigInts
- Fix moderation service tests to pass config as parameter

Breaking Changes:
- Removes legacy file-based configuration system
- API now returns database format with string values for BigInt fields
