refactor(app): extract composer-actions module with pure tests

Move composer cancel/queue/attachment/dispatch orchestration out of
composer.tsx into a React-free actions module. The module takes its
dependencies (send client, queue writer, stream writer, attachment
persister, image picker) as injected ports, so the new
composer-actions.test.ts can drive every action with inline fakes —
zero vi.mock of internal modules, zero JSDOM, zero React.

The old composer.test.tsx (heavy mocked component test) is removed
and replaced with composer-actions.test.ts (31 unit tests).

Also extract isWorkspaceAttachment / userAttachmentsOnly /
workspaceAttachmentToSubmitAttachment from composer-workspace-attachments.tsx
into a sibling .ts so the actions module (and composer-attachments.ts)
can use them without dragging React/RN/lucide into a pure test graph.
