PR-10c Bank Composition Section Shell and Form Session Integration

Domain owner: docs/studio

Briefing

Add the Bank Composition section shell into Asset Details, aligned with Runtime Contract and the existing StudioFormSession section rhythm.

This slice lands the visible section and its staged-edit shell contract before full family-specific behavior is wired.

Objective

After this PR:

• Asset Details contains a real Bank Composition section;
• the section is a VBox section aligned with the existing details composition;
• the section mirrors the Runtime Contract shell as closely as practical;
• the section exposes change, apply, reset, and cancel;
• outside editing it renders persisted state in read-only mode;
• before behavior wiring is complete it can still render disabled/read-only internals instead of looking absent.

Dependencies

• ../decisions/Bank Composition Section Shell Decision.md
• ./PR-10a-bank-composition-details-dto-projection.md
• ./PR-10b-bank-composition-base-components.md
• ./PR-07c-asset-details-and-form-lifecycle.md

Scope

• add the Bank Composition section to Asset Details
• align the shell with Runtime Contract
• integrate StudioFormSession staged-edit lifecycle at the section boundary
• render read-only or disabled internals when behavior is incomplete
• show persisted state outside edit mode

Non-Goals

• no family-specific bank rules yet
• no final section-scoped coordinator yet
• no workspace-bus events yet
• no packer apply write path yet

Execution Method

1. Introduce the section host into Asset Details.
2. Reuse the existing section/action-bar rhythm from Runtime Contract.
3. Bind the section shell to a StudioFormSession lifecycle.
4. Render read-only state outside edit mode.
5. Render disabled/read-only internals where behavior is still pending.

Acceptance Criteria

• the Bank Composition section is visible in Asset Details
• the section shell matches the existing details-section rhythm
• change, apply, reset, and cancel are part of the shell contract
• outside edit mode the section shows persisted state in read-only form
• the section does not appear blank or absent while later slices are still pending

Validation

• unit tests for section visibility and shell state
• unit tests for StudioFormSession-driven shell transitions
• UI smoke validation for read-only and editing shell modes
