catalog-contract: section_groups + Field.section for progressive disclosure; ace-step v2

asset_engine consumer (althing thread 01KRCJF7NGMXYE9F62Q1A6KFD4)
needed structure for ace-step's 27-field form. Two additive Pydantic
changes — backward-compatible, no catalog_version bump per the
policy table:

  - CatalogField.section: str | None = None
  - CatalogService.section_groups: list[CatalogSectionGroup] = []
  - new CatalogSectionGroup model: {id, label, hint?}

Validator: every Field.section value must reference a declared
section_groups[].id within the same service; section_groups[].id
values are unique. CATALOG-CONTRACT.md updated with both the new
service-fields row and a versioning-policy row covering
"add optional Field/Service keys -> no bump."

ace-step entry rewritten to use the new schema:
  - bumped version 1 -> 2
  - declared 6 section groups (basic / generation / conditioning /
    a2a / lora / output) with hints
  - tagged every field with a section
  - added previously-missing checkpoint_path (required: true,
    default: "/app/checkpoints" — the container's mount path).
    Wrapper-side cleanup (default in infer-api.py) queued as
    follow-up.
  - changed lyrics from optional: true -> required: true with
    default "" to match upstream's `lyrics: str` shape (empty
    string satisfies it).

JSON Schema regenerated.

Pydantic-model side of this change lives in asset_engine at
src/asset_engine/catalog.py — committed there separately.

Required by the upstream wrapper (`infer-api.py:29`, no default in
the Pydantic model). The container always mounts checkpoints at
/app/checkpoints, so the catalog default works out-of-the-box.
Only override if you've mounted an alternate checkpoint path.
Wrapper-side cleanup queued — once the upstream model defaults this,
the catalog field will become optional or be dropped entirely.
