Fix database schema documentation to match actual tables

- Fix table names: pc_comm_config → commconfig, pc_dnc_config → dncconfig
- Fix column name: communications.gateway → defaultgateway
- Clarify printers uses 'ipaddress' while communications uses 'address'
- Update CREATE TABLE statements to match actual schema
- Add warranties table to QUICK_REFERENCE.md
