feat(moderation): enhance message capture and storage with thread support

- Added functions to retrieve message location, sticker metadata, and display content in messageCapture.ts.
- Updated captureMessage function to store thread information and sticker metadata in the database.
- Modified messageStore.ts to support querying messages and attachments by thread ID.
- Updated types.ts to include thread_id in AttachmentRecord.
- Altered database schema in muxer-queue.ts to add thread_id column to attachments.
- Introduced ChannelSummary interface and listWatchableChannels method in voiceController.ts to fetch watchable channels.
- Added API endpoint in webserver.ts to retrieve channels for a given guild.
