Refactor code for improved readability and consistency across various command files

- Adjusted formatting and indentation in `rename.rs`, `suggestion.rs`, `tempvoc.rs`, `ticket.rs`, `ticket_member.rs`, and `tickets.rs` for better clarity.
- Consolidated `if` statements and method calls for cleaner code in `suggestion.rs`, `tempvoc.rs`, and `ticket.rs`.
- Updated the `LOGS_PER_PAGE` constant in `viewlogs.rs` to increase the number of logs displayed per page.
- Removed unused `handle_boostembed` function from `logs_service.rs`.
- Added new modules in `mod.rs` for better organization of command files.
- Enhanced the `handle_show_pics` function in `showpics.rs` for improved member filtering.
- Updated the `handle_message` function in `message_event.rs` to streamline command handling.
