fix(server): add relationTargetFieldMetadataId column early in upgrade sequence (#20664)

## Summary

Cross-version upgrade fails at the 2.3
`DropMessageDirectionFieldCommand` stage:

```
[QueryFailedError] column ViewFilterEntity.relationTargetFieldMetadataId does not exist
  at WorkspaceFlatViewFilterMapCacheService.computeForCache
```

(see
https://github.com/twentyhq/twenty-infra/actions/runs/25929264129/job/76219964380)

Same shape as #20584 (subFieldName), one column over.

### Root cause

1. The 2.3 `DropMessageDirectionFieldCommand` builds a workspace
migration that deletes a `fieldMetadata` (the `direction` field).
2. `WorkspaceMigrationRunnerService.run` walks the metadata cascade
graph and pulls `viewFilter` into the dependency set because
`viewFilter` is the inverse one-to-many of `fieldMetadata`.
3. That maps to cache keys → `flatViewFilterMaps` gets requested →
`WorkspaceFlatViewFilterMapCacheService.computeForCache` runs.
4. `computeForCache` does `viewFilterRepository.find({ where: {
workspaceId }, withDeleted: true })` with no `select`, so TypeORM emits
a SELECT that includes `relationTargetFieldMetadataId` — column only
added by the 2.6 fast instance command `1798000005000`, not yet run at
the 2.3 stage. 💥

### Why v2.5.0 / v2.5.1 passed

They didn't include #20527 (one-hop relation filters, May 14), which
added `relationTargetFieldMetadataId` to `ViewFilterEntity` and the 2.6
instance command. The CI base image (v1.22) seeded the DB, then the
v2.5.0/v2.5.1 container ran upgrade commands against an entity that
didn't yet know about this column.
