Review: Monitor slider/list config

This PR cleanly adds slider (mode 3) and list (mode 4) configuration fields (sliderMin, sliderMax, isDiscrete, width, height) to the Monitor widget model. The implementation is well-structured:

• New fields are kept in sync across MonitorInits, RawMonitorConfig, the class, the constructor, clone(), and export().
• load() correctly lets the new fields flow through ...inits into the constructor (verified by the round-trip tests).
• Test coverage is strong: defaulting, mode-conditional export presence/absence, and full load → export → JSON round-trip → load cycles.

No blocking issues. A few points below are worth a deliberate decision. No performance concerns; the new fields carry no security-critical impact (client-side display config only).
