Switch Plot Package from TLF to OSPSuite.plots

[KatrinCoboeken]

Summary

This package currently contains three workflows: QualificationWorkflow, MeanModelWorkflow, and PopulationWorkflow.

• MeanModelWorkflow and PopulationWorkflow will be migrated to the ospsuite reporting framework (package: ospsuite.ReportingFramework). For these two workflows we need proper lifecycle management including a reliable stop operation.
• QualificationWorkflow currently uses plots based on TLF. All these plots must be replaced by equivalents from ospsuite.plots. Some plot functions live in ospsuite-R and call TLF internally; those helpers must replaced to use the ospsuite-R plotfunction which use ospsuite.plots.

Goals

• Add lifecycle management with a stop action for MeanModelWorkflow and PopulationWorkflow.
• Replace all TLF-based plots used by QualificationWorkflow with ospsuite.plots equivalents.
• Replace plot helper functions in ospsuite-R that depend on TLF so they use ospsuite.plots.
• Provide tests and documentation for the changes.

Scope

• Replace plotting code only for QualificationWorkflow (no change to the workflow logic unless required to support new plotting API).
• Implement lifecycle stop in MeanModelWorkflow and PopulationWorkflow so they can be cleanly halted when replaced by ospsuite reporting.
• Update helper functions in ospsuite.R used by other parts of the package.

Tasks (checklist)

• Implement a safe stop operation that halts in-progress computation and releases resources
• Add unit/integration tests for stop (simulate long-running tasks, resource cleanup)
• Add lifecycle management to PopulationWorkflow
  • Implement stop operation and tests (same as above)
• Inventory all plots in QualificationWorkflow that call TLF
  • Create a list mapping current TLF calls to ospsuite.plots equivalents (or required transformations)
• Update ospsuite.R helper plot functions
  • Replace internal TLF calls with ospsuite.plots or refactor to delegate to ospsuite.plots
  • Update signatures and callers if necessary; ensure backward compatibility where practical
  • Add unit tests for helpers
• Replace TLF calls in QualificationWorkflow plots with ospsuite.plots
  • Preserve plot semantics (titles, labels, legends) or document differences
  • Add/adjust tests to confirm rendering & data correctness
• Documentation & migration notes
  • Update README/docs to state that MeanModelWorkflow and PopulationWorkflow are handled via the ospsuite reporting framework and support lifecycle stop
  • Document that QualificationWorkflow now uses ospsuite.plots
