feat: Improve daily recap functionality

- Changed the daily recap time to 22:00.
- Modified the `send_daily_recap` function to split the recap message into multiple messages if it exceeds 2000 characters to avoid hitting the Discord message length limit.
- Added a 1-second delay between each message chunk to avoid rate limiting.
