Remove unused MQTTMessageBuilder members (getPacketTypeString,
formatTimestamp/Time/Date stubs, JSON_BUFFER_SIZE constant) for a
small flash saving with no behavior change.
Replace the per-byte snprintf("%02X") in bytesToHex with a nibble
lookup table, avoiding a format-string parse up to ~512x per publish
on the MQTT task. Output is byte-for-byte identical uppercase hex.
