v1.14.2: System Configuration sub-device
New "System Configuration" sub-device for main.xml feature entities.
Parses INPUTV (page visibility), INPUTD (device flags), and INPUTMZ (mixed-zone flags) from main.xml as settable switch entities under a dedicated sub-device.
Example entities:
- SYSCONFIG-PAGE1-VISIBLE: Toggle Radiatory page visibility
- SYSCONFIG-PAGE55-VISIBLE: Toggle FVE page visibility
- SYSCONFIG-DEVICE-FLAG: Device-level configuration flag
- SYSCONFIG-MIXED-ZONE: Mixed zone enabled
Also: set_value() now accepts optional internal_name parameter to skip redundant page fetch when the NAME is already known (used for SYSCONFIG entities whose NAME comes from main.xml INPUTV/INPUTD/INPUTMZ elements that are not standard INPUT elements).
154 tests pass, 0 failures.
