## Summary
- Replaces the standalone TypeORM migration
`1775654781000-addConditionalAvailabilityExpressionToPageLayoutWidget.ts`
with a registered fast instance command under
`packages/twenty-server/src/database/commands/upgrade-version-command/1-23/`,
so the `pageLayoutWidget.conditionalAvailabilityExpression` column is
created through the unified upgrade pipeline.
- Uses `ADD COLUMN IF NOT EXISTS` / `DROP COLUMN IF EXISTS` so the new
instance command is a safe no-op for environments that already applied
the previous TypeORM migration.
- Keeps the original timestamp `1775654781000` so the command slots
chronologically into the existing 1.23 sequence; auto-discovered via
`@RegisteredInstanceCommand`, no module wiring needed.
## Context
Reported error when creating a new workspace on `main`:
> column PageLayoutWidgetEntity.conditionalAvailabilityExpression does
not exist
Aligns this column addition with the rest of the 1.23 schema changes
that already use the instance-command pattern.
