feat: implement short ID mapping for BlueBubbles messages and enhance reply context caching

- Added functionality to resolve short message IDs to full UUIDs and vice versa, optimizing token usage.
- Introduced a reply cache to store message context for replies when metadata is omitted in webhook payloads.
- Updated message handling to utilize short IDs for outbound messages and replies, improving efficiency.
- Enhanced error messages to clarify required parameters for actions like react, edit, and unsend.
- Added tests to ensure correct behavior of new features and maintain existing functionality.
