fix(ci): clear three pre-existing main CI failures uncovered by the green-up

Getting FR-019 + the @summary rollout green unblocked the conformance steps, which
then surfaced the NEXT layers of main's accumulated red (each had been masked by an
earlier failure aborting the step). All three are pre-existing on main, unrelated to
FR-019:

1. TS conformance — docs-command.test.ts asserted `## Constraints`, but main's docs
   refactor (88dfc3e "merge Storage + Constraints into a single neutral Fields
   table") removed that section and only updated docs-neutrality.test.ts, leaving
   this CLI test stale. Re-point it at the surviving neutral `## Fields` section.

2. Python conformance — `uv run pytest test_validation_conformance.py` failed with
   ModuleNotFoundError: pydantic. `uv run` installs [dependency-groups], which held
   only pytest; pydantic lived in [project.optional-dependencies]. Add pydantic to
   the dev dependency-group and relock (uv.lock was also stale at 0.7.0 → 0.9.0).

3. release-gate (java/kotlin) — `mvn -f integration-tests/pom.xml test` could not
   resolve com.metaobjects:*:7.3.0-SNAPSHOT: integration-tests is excluded from the
   reactor and the SNAPSHOT jars aren't on Maven Central, but the script never
   installed them to .m2 first (it used to resolve the released 7.2.0; main's bump to
   7.3.0-SNAPSHOT broke it). integration-test.sh now installs the module deps
   serially (-T clobbers the shared render jar) before each docker-only run.

Verified locally: TS codegen-ts+cli+migrate-ts 1605/0; full Python CI sequence via
`uv run` (conformance 267, render 254, validation 9, cli-registry 5); both Maven
install lists build. With the earlier commits this takes the PR — and main — green.
