fix(spec): title SelectOptionSchema's six row properties

Studio renders a `type: 'repeater'` form field as a table whose column
headers read `items.properties[k].title ?? k` off the JSON Schema derived
from the metadata type schema. `SelectOptionSchema` carried no `title` on
any of its six row properties, so the fallback arm ran and the property
panel printed the raw machine keys — in every locale, English included.

Add `.meta({ title })` to `label`, `value`, `description`, `color`,
`default` and `visibleWhen`, and delete this carrier's two entries from
the shrink-only `repeater-item-titles` ledger. One edit clears both:
`field:options` and `object:fields.options` resolve to the SAME
`SelectOptionSchema` object — `FieldSchema.options` is
`z.array(SelectOptionSchema)` and `object.fields` is a record of that same
`FieldSchema` — verified by object identity, not assumed.
