feat: Refactor channel management and UI components

- Removed hardcoded channel data from `channel.ts` and replaced it with a dynamic channel dictionary.
- Introduced a new Pinia store `channel.ts` to manage selected and available channels.
- Reworked `AddChannelDialog.vue` to allow users to search and select channels dynamically.
- Updated `TaskCenter.vue` to utilize the new channel store and handle empty channel selections gracefully.
- Enhanced IPC communication for loading and saving selected channels in the configuration.
- Adjusted `runTaskOperationService.ts` to ensure proper handling of channel data.
- Improved styling and structure of UI components for better user experience.
