feat(12.1-02): writable foreign keys, locked relation options, invisible columns

- FieldRelationContract.WritableForeignKey makes a belongsTo field over a
  protected foreign key writable; the protected key list is unchanged
- cabana.RelationLockProvider names related ids an administrator may not add
  or remove: options and labels carry locked, and a create or update that
  changes the locked subset is 403 before any row is written
- columns.yaml invisible keeps a column searchable and out of the rows
- a controller implementing pact.FilterOptions serves a scope filter's
  choices before the model
- SPA: locked chips and options in RelationField, DataTable skips invisible
  columns
- README, docs, OpenAPI document, TS types and dist updated
