Refactor Discord channel resource management and update imports

- Consolidated channel type definitions by moving them to discord-channel-types.ts for better organization.
- Removed redundant DASHBOARD_CHANNEL_TYPES and updated exports to streamline channel handling in the application.
- Enhanced type safety by utilizing the ChannelKind type in the discord-channel-select component.
