feat: enhance message handling with short ID resolution and reply context improvements

- Implemented resolution of short message IDs to full UUIDs in both text and media sending functions.
- Updated reply context formatting to optimize token usage by including only necessary information.
- Introduced truncation for long reply bodies to further reduce token consumption.
- Adjusted tests to reflect changes in reply context handling and message ID resolution.
