[Part 1 / Phase 3] PathogenTestForm: Refactor TuberculosisDiseaseSectionLayout

[roldy]

Problem Description

Context

Part of Epic: [Epic] PathogenTestForm: Composition + Stable Form Refactor
Blocked by: Phase 2

Refactor TuberculosisDiseaseSectionLayout to use the new clean interface signatures.
Remove all bridge method calls (form.addSectionField(...), form.getCurrentDisease(), etc.)
and delegate tube logic to a forthcoming TubeFieldHandler.

Proposed Solution

Tasks

• Remove all form.addSectionField(...) / form.removeSectionField(...) calls
• Use fieldGroup.buildAndBind(...) + panel.addComponent(...) directly
• Wire Luxembourg visibility via FieldHelper.setVisibleWhen(fieldGroup, ...) — capture registrations for cleanup in unbindFields()
• Stub TubeFieldHandler usage (can use placeholder until Phase 6)
• Implement onTestTypeChanged():
  • Call drugSusceptibilityField.updateFieldsVisibility()
  • Apply Luxembourg-specific auto-result rules for IGRA test type

Additional Information

Acceptance Criteria

• No import of PathogenTestForm
• bindFields / unbindFields / onTestTypeChanged all use only FieldGroup + CustomLayout + standard types
• Luxembourg IGRA visibility rules still work correctly
• mvn compile -pl sormas-ui passes
