[V2][team] Multi-Agent Assignment - UI and accessibility surface

[kryputh]

Goal

Create the tool's local user interface surface with accessibility built in.

Tool: Multi-Agent Assignment

Release tier: V2

Audience: team

Required labels

This issue must carry these campaign labels:

• GrantFox OSS
• Maybe Rewarded
• Official Campaign
• Tooling Ecosystem
• V2 Later Tool
• Team Tool

Implementation folder

All work for this issue must stay inside:

text tools\v2\team\multi-agent-assignment/

V2 later-release tool. Build the tool as complete isolated work, but do not link it to the main app yet.

Do not modify the main application shell, dashboard layout, navigation system, authentication, wallet core, mail rendering engine, existing inbox architecture, existing routing, Stellar integration core, database schema, or existing design system.

Deliverables

• Create folder-local components for the primary tool workflow.
• Add empty, loading, error, and success states.
• Include keyboard, focus, labeling, and screen-reader considerations.

Acceptance criteria

• The UI is isolated to the tool folder and is not mounted in the main app.
• Interactive controls have labels, focus behavior, and keyboard support.
• The visual style is documented without changing the shared design system.
• Files changed by this issue are limited to $rel/.
• The contribution is reviewable as a self-contained mini-product change.

OSS contributor notes

Keep the work small and reviewable. Prefer local fixtures, local docs, local tests, and folder-local components/services/hooks. If the tool needs a future connection to the main mail app, write that as a follow-up issue instead of adding the integration here.
