feat(spec): remove first batch of dead metadata props (#2377, A2)

Cleanly-verifiable, unique-named dead props with zero footprint outside spec:
- field: caseSensitive, maxRating
- object: partitioning (+PartitioningConfigSchema), defaultDetailForm

Liveness ledgers (field/object) updated; api-surface regenerated (drops
PartitioningConfig type only). softDelete + measures.certified deferred (set in
non-spec test fixtures); overloaded-name candidates deferred (see #2377).

Verified: full spec suite green; check:api-surface ✓; liveness gate ✓;
no non-spec usage of the four removed props.

+Remove a first batch of dead (unenforced, unauthored) metadata properties (#2377, ADR-0049).
+
+Verified set 0× / read 0× across framework + objectui + cloud + hotcrm + templates, with no test footprint outside `@objectstack/spec`:
+
+- **field**: `caseSensitive`, `maxRating`
+- **object**: `partitioning` (+ `PartitioningConfigSchema`), `defaultDetailForm`
+
+Liveness ledgers (field/object) updated; api-surface regenerated (drops `PartitioningConfig`/`PartitioningConfigSchema` only). Folded into the 11 line (`minor`).
+
+The remaining #2377 candidates are deliberately not in this batch: overloaded names (`tags`/`active`/`versioning`/`dependencies`/`index`/…) need per-occurrence handling, and `softDelete` / `measures.certified` turned out to be set in non-spec test fixtures (analytics, mcp) — both deferred. See the issue for the full split.
