**What** Adds a 2.19 workspace upgrade command that backfills missing FieldActorSource enum values (AGENT) into the Postgres enums backing every ACTOR composite field (createdBy, updatedBy) across all existing workspaces. Each ACTOR field stores its source sub-field as a Postgres enum scoped to its own table and schema (e.g. workspace_abc.company_createdBySource_enum). Workspaces created before these enum values were introduced are missing them, which causes runtime errors when those sources are used. **How** buildActorSourceEnumBackfillTargets collects all ACTOR fields from the workspace metadata cache and maps each enum sub-property to its (tableName, columnName, enumName, expectedValues) tuple. Before iterating over all targets, the command performs a single fast pg_catalog.pg_enum lookup on company.createdBySource as a representative sentinel. If AGENT is already present there, the workspace is skipped entirely (idempotency fast-path). For each remaining target, ALTER TYPE … ADD VALUE IF NOT EXISTS is issued per missing value via WorkspaceSchemaEnumManagerService.addEnumValue, making the command fully idempotent and safe to re-run.
