Subject: [PATCH] fix(canvas/a11y): aria-hidden SVGs, MissingKeysModal
 semantics, session cookie auth (#1744)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. f675500: aria-hidden="true" on decorative SVG icons in
   DeleteCascadeConfirmDialog warning icon and Toolbar stop/restart
   /search/help icons. All have adjacent aria-label text or parent
   button aria-label — correct.

2. eb87737: session cookie auth fallback for /registry/:id/peers
   SaaS canvas path. verifiedCPSession() checked after bearer token
   in validateDiscoveryCaller, allowing canvas to hit the Peers tab
   via session cookie rather than bearer token. Self-hosted bypass
   logic preserved.

3. 80fedd6: MissingKeysModal dialog semantics — role="dialog",
   aria-modal="true", aria-labelledby="missing-keys-title",
   requestAnimationFrame focus management. Also removes stale
   aria-describedby={undefined} from CreateWorkspaceDialog.
