feat(workflow): add universalIdentifier + applicationId to core workflowVersion (#22747)

## workflowVersion core: syncable columns

Adds `universalIdentifier` + `applicationId` (nullable) to
`core.workflowVersion`, plus the FK to `core.application` and the
`(workspaceId, universalIdentifier)` unique index, via a 2.20
add-columns fast command gated with `@WasIntroducedInUpgrade`.

Nullable for now: the already-merged Phase A backfill (#22663) inserts
version rows without these columns, so `applicationId` can't be NOT NULL
yet. Flipping to NOT NULL + `extends SyncableEntity` comes once they're
populated (backfill + dual-write follow-ups).

Schema captured and verified via `migrate:generate` (zero drift).

Independent of the core-workflow PR, but both add 2.20 upgrade commands,
so this one (ts `…480`) must merge **after** the core-workflow PR (ts
`…479`), or it gets re-timestamped on rebase.
