refactor: clean labkit ui api surface

[Pluze]

Scope

Clean the migration-era LabKit UI API surface in one branch with phased commits:

• remove createShell shellOptions and panel/draw/update aliases
• remove plotOptions and topBottomPlotControls from labkit.ui.view.panel
• move app-specific top/bottom plot controls and right-side axes pairs into app-owned UI packages
• remove createShell dualPlot/rightKind/showPlotControls/title specialization
• require structured labkit.ui.view.form specs and remove raw args/shorthand passthrough

Validation

• git diff --check
• scripts/run_matlab_tests.sh testLabkitUiGui
• scripts/run_matlab_tests.sh testAppsElectrochemGui
• scripts/run_matlab_tests.sh testAppsDicGui
• scripts/run_matlab_tests.sh testAppsImageMeasurementGui
• scripts/run_matlab_tests.sh testAppsGui
• scripts/run_matlab_tests.sh testProject

Notes

• Kept app-specific Plot Options sections/local option structs; only the LabKit panel facade was removed.
• Kept form kind info as a structured spec because it has row+label layout semantics distinct from readonly.
• Interactive GUI workflow feel was not manually verified; automated GUI coverage is structural.
