Add general-purpose script for deleting dangling data values

[Ramon-Jimenez]

Summary

• Adds a new delete-dangling-data-values.ts script that replaces the old delete-wrong-data-values.ts, which was hardcoded to a specific DHIS2 instance and COVID-specific category combos.
• Reuses the existing ProjectDb.getDanglingDataValues() detection logic, which identifies data values whose (dataElement, categoryOptionCombo) pair no longer matches the project's current configuration.
• Works across all projects or a specific one via --project=ID.
• Two-step workflow: --generate writes a report + delete payload for review, --post executes the deletion.

Usage

# Step 1: Generate report (dry run)
yarn ts-node src/scripts/delete-dangling-data-values.ts --url=https://dhis2-instance.org --generate

# Or for a specific project:
yarn ts-node src/scripts/delete-dangling-data-values.ts --url=https://dhis2-instance.org --generate --project=PROJECT_ID

# Step 2: Review the generated files in src/scripts/data/
#   - dangling-data-values-report.json (human-readable)
#   - dangling-data-values-to-delete.json (DHIS2 delete payload)

# Step 3: Delete after review
yarn ts-node src/scripts/delete-dangling-data-values.ts --url=https://dhis2-instance.org --post

Context

A client reported that after removing and re-adding an indicator from a project, "dangling" data values remained in the DHIS2 database. These orphaned values were still visible in their Tableau extracts from the DHIS2 PostgreSQL. The app already detects and notifies about dangling data (via ProjectNotification), but had no general-purpose tool to clean them up.

Test plan

• Type-checks cleanly
• All existing tests pass (47/47)
• Run --generate against a test DHIS2 instance and verify the report is accurate
• Run --post and verify dangling values are removed from DHIS2
