znetsixe bc8138c3dc fix(charts): add all required FlowFuse ui-chart properties + document in rule set ...

Charts rendered blank because the helper was missing 15+ required
FlowFuse properties. The critical three:
  - interpolation: "linear" (no line drawn without it)
  - yAxisProperty: "payload" + yAxisPropertyType: "msg" (chart didn't
    know which msg field to plot)
  - xAxisPropertyType: "timestamp" (chart didn't know the x source)

Also: width/height must be numbers not strings, colors/textColor/
gridColor arrays must be present, and stackSeries/bins/xAxisFormat/
xAxisFormatType all need explicit values.

Fixed the ui_chart helper to include every property from the working
rotatingMachine/examples/03-Dashboard.json charts. Added the full
required-property template + gotcha list to the flow-layout rule set
(Section 4) so this class of bug is caught by reference on the next
chart build.
