Summary

This PR introduces a new way to browse drugs by category while preserving the existing search‑based workflow.

1. Drug Categories via Concept Sets
Drugs can be grouped into configurable categories using Concept Sets, which are managed via Legacy Admin. These Concept Sets define how drugs are grouped and can be adapted to local needs (for example, by program, formulary, or service). Each category corresponds to a Concept Set containing the relevant drug concepts.

2. List Tab for Browsing Drugs
The drug selection UI has been enhanced with a new List tab, available alongside the existing Search tab (which remains the default). The List tab allows users to browse drugs by selecting a category, making it easier to discover medications without knowing their exact names.

3. Configuration via Implementer Tools
Implementers can control which categories appear in the List tab by configuring Concept Set UUIDs under the drugCategoryConceptSets setting in @openmrs/esm-patient-medications-app via Implementer Tools. Only the configured Concept Sets are exposed to users.
