Add server info commands: /time, /played, and /who

- Add CMSG_QUERY_TIME (0x1CE) and SMSG_QUERY_TIME_RESPONSE (0x1CF) opcodes
- Add CMSG_REQUEST_PLAYED_TIME (0x1CC) and SMSG_PLAYED_TIME (0x1CD) opcodes
- Add CMSG_WHO (0x062) and SMSG_WHO (0x063) opcodes
- Implement /time command to query and display server time
- Implement /played command to show total and level playtime statistics
- Implement /who [name] command to list online players with level and guild
- Add packet builders: QueryTimePacket, RequestPlayedTimePacket, WhoPacket
- Add response parsers for all three server info packet types
- Add handlers that format and display responses in chat as system messages
- Format played time as "X days, Y hours, Z minutes" for readability
- Format server time as "YYYY-MM-DD HH:MM:SS" for readability
