## Problem
The `2.17` `AddWorkspaceMemberJobTitleField` upgrade command failed for
every workspace that has a **custom field on `workspaceMember`** (it
aborted the per-workspace upgrade sequence). Root cause:
The command used `FieldMetadataService.createManyFields`, which —
besides creating the field metadata — also creates the new field's
**view fields** across the object's existing views. Validating a
view-field creation enumerates the target view's full
`viewFieldUniversalIdentifiers`, which includes view fields owned by
**another application** (a custom field a user added to
`workspaceMember`). Those cross-application view fields are filtered out
of the build's application-scoped dependency maps, so the build throws
`Could not find flat entity with universal identifier ...`.
## Fix (command-scoped)
Create the field metadata **only — no view fields** — sourced from the
standard-application definition, mirroring
`AddInactiveGenericStandardFieldsCommand` (which adds a standard field
the same way and is unaffected by this bug). The standard view-field
side effects are reconciled as code, so they should not be produced at
runtime here.
Concretely: source the standard `jobTitle` `FlatFieldMetadata` from
`computeTwentyStandardApplicationAllFlatEntityMaps`, blank its
`viewFieldIds` / `viewFieldUniversalIdentifiers`, and run a
`fieldMetadata`-only `validateBuildAndRunWorkspaceMigration` instead of
`createManyFields`. Also drops the now-unused `FieldMetadataModule`
import from the 2-17 command module.
## Trade-off
Existing workspaces get the `jobTitle` field + column but **no view
field**, so it won't appear as a default column in `workspaceMember`
views until the standard-application reconciliation adds view fields.
`jobTitle` is `isSystem` / `isUIReadOnly`, so this is acceptable as the
immediate unblock.
## Scope
This is the small, immediate unblock for the failed `2.17` upgrade. The
general framework fix (load cross-application children of involved
parents into the build scope) is tracked separately in #22294.
