## Summary Removes gauge chart from the chart-type picker and deletes existing gauge widgets via a workspace migration. The gauge was rendering a hardcoded `0.7 / "Progress"` stub regardless of configuration -- never wired to real data. The contract stays in place. We keep `WidgetConfigurationType.GAUGE_CHART`, the DTO, the GraphQL union member, and the gauge folder -- so stored gauge JSON still resolves through the schema. The render path falls through to `default: return null`, so any un-migrated gauge widget renders as an empty cell, not a crash. This PR just removes existing gauge widgets if there are any (via `upgrade:2-3:delete-gauge-widgets`). The deliberate cleanup -- deleting the type definitions, the gauge folder, the DTO -- comes in a follow-up PR after the migration has run. --------- Co-authored-by: Charles Bochet <charles@twenty.com>
