fix(canvas/a11y): aria-hidden SVGs, MissingKeysModal dialog semantics, session cookie auth

Three fixes cherry-picked from issue #1744:

1. aria-hidden on decorative SVG icons:
   - DeleteCascadeConfirmDialog.tsx: warning triangle SVG gets aria-hidden="true"
   - MissingKeysModal.tsx: warning triangle SVG gets aria-hidden="true"
   Both are purely decorative; adjacent text labels provide context.

2. MissingKeysModal dialog semantics:
   - role="dialog", aria-modal="true", aria-labelledby="missing-keys-title" on modal
   - id="missing-keys-title" added to the h3 heading
   - requestAnimationFrame focus trap: auto-focus title element when modal opens
   - Also removes stale aria-describedby={undefined} from CreateWorkspaceDialog.tsx

3. Session cookie auth for /registry/:id/peers:
   - Promotes VerifiedCPSession() fallback before the bearer token branch
   - Fixes SaaS canvas Peers tab 401 — canvas hits this endpoint via session cookie
   - Correctly returns "invalid session" for bad cookies instead of falling through
   - Self-hosted bypass logic preserved

Test fix (bundled, same branch):
   - ContextMenu keyboard test: add getState() stub to useCanvasStore mock
   - Required after ContextMenu.tsx gained a direct getState() call at line 169
