Add comprehensive packet boundary debugging for quest opcodes

Browse source 
Logs for opcodes 0x18F, 0x18D, 0x188, 0x186:
- Raw header bytes (size + opcode)
- Total packet size vs buffer size
- Payload hex dump (first 16 bytes)
- Next packet header preview

This will reveal packet desync issues, wrong size fields, or
incorrect opcode mappings.
