Pull request overview
This PR implements a pagination system for the /m list command to handle large message lists more effectively. The implementation adds support for viewing messages in pages of 10 items with navigation hints.
Key Changes:
- Added pagination parameters (page and pageSize) to all message listing methods in Mailbox.java
- Modified ListCommand.java to parse optional page numbers from command arguments
- Updated help text to reflect the new command syntax

Creating a new SimpleDateFormat instance on every iteration is inefficient. Consider creating the SimpleDateFormat instance once before the loop to improve performance, especially when displaying multiple messages.

The pagination logic is duplicated across three methods with only minor variations (message type and navigation commands). Consider extracting this common logic into a private helper method that accepts the message list and message type as parameters. This would reduce code duplication and make the code more maintainable.

The page size value of 10 is hardcoded in multiple places. Consider extracting this as a private static final constant (e.g., DEFAULT_PAGE_SIZE) in the Mailbox class to improve maintainability and make it easier to adjust if needed.

The page size value of 10 is hardcoded here. This should be extracted as a constant to maintain consistency with other occurrences of the same value and improve maintainability.
