docs(types): finish the ObjectTable -> ObjectGrid rename in two stale doc comments (#2947)

Follow-up to #2938. `ObjectTable` is not a typo but a historical artifact:
the component was renamed to `ObjectGrid` long ago (see the "ObjectTable:
Auto-generates tables from ObjectQL object schemas" entries still recorded
in the package CHANGELOGs), and some prose never followed.

#2938 fixed the one occurrence that actually bit authors — the `kind:'react'`
page scope comment, where the prose *is* the API documentation for a
runtime-derived scope. These two are lower-stakes descriptive prose on type
definitions, cleaned up so the dead name stops surviving in live code:

  - field-types.ts  — the module doc for the field type system.
  - objectql.ts     — `ObjectViewSchema`. Factually correct as well as
                      mechanical: ObjectView renders an `object-grid`
                      (plugin-view/src/ObjectView.tsx:858).

`ObjectTable` now appears only in the package CHANGELOGs (immutable history),
gitignored `dist/` output, and sdui-parser's synthetic compiler fixtures.

Comment-only; no behavior change.
