refactor: migrate all code to use getGuildConfig() for guild settings

- Update all commands and events to fetch guild config once per execution
- Pass config to service methods that need it (ModerationService.issueWarning)
- Update terminal service to use guildSettingsService for persistence
- Remove direct imports of config for guild-specific settings

This consolidates configuration to database-backed guild settings,
eliminating the dual config system.
