fix(canvas/test): Spinner tests use getAttribute for SVG className

SVG elements in jsdom expose className as SVGAnimatedString (an object), not a plain string. Calling toContain() on an object produces a confusing "expected [] to include" error. Fix: use getAttribute("class") instead. Also adds afterEach(cleanup) for DOM isolation between tests. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
fix(canvas): extractMessageText uses only first direct text field

-// Background (#2872 + post-2026-05-06 follow-up):
-//   - Migration 20260506000000_workspaces_unique_parent_name added a
-//     partial UNIQUE index on (COALESCE(parent_id, sentinel), name)
-//     WHERE status != 'removed'. It exists to close the TOCTOU race in
-//     /org/import that previously let two concurrent POSTs both INSERT
-//     the same (parent_id, name) row.
-//   - /org/import handles the constraint via `ON CONFLICT DO NOTHING`
-//     + idempotent re-select (handlers/org_import.go).
-//   - The Canvas Create handler (handlers/workspace.go) did NOT — a
-//     duplicate POST returned an opaque HTTP 500 with the raw pq error
-//     in the server log. Repro path: user clicks a template card twice
-//     in canvas before the first response paints.
-//
-// Resolution: auto-suffix the user-typed name on collision. The
-// uniqueness constraint required for #2872 stays in place; only the
-// Canvas Create path's reaction to it changes. Names become a
-// free-form display label that the platform disambiguates; row
-// identity is carried by the workspace id (UUID).
-//
-// Suffix shape: " (2)", " (3)", … up to N=maxNameSuffix. Chosen over
-// numeric "-2" / "_2" because the parenthesised form is the standard
-// disambiguation pattern users already expect from Finder / Explorer
-// / Google Docs / file managers. Stays under the 255-char name cap
-// (#688 — validated by validateWorkspaceFields) for any reasonable
-// base name; parens are not in yamlSpecialChars so the existing YAML-
-// safety guard is unaffected.

-// the helper's retry contract under a fake driver error, but only
-// a real Postgres can confirm:
-//
-//   - The migration 20260506000000 actually created the index.
-//   - lib/pq emits SQLSTATE 23505 with Constraint =
-//     "workspaces_parent_name_uniq" (not a synonym, not the message
-//     fallback).
-//   - The COALESCE(parent_id, sentinel) target collapses NULL
-//     parent_ids so two root-level workspaces with the same name
-//     collide as the migration intends.
-//   - The WHERE status != 'removed' partial filter exempts
-//     tombstoned rows from blocking re-use.
-//
-// Per feedback_mandatory_local_e2e_before_ship: ship-mode requires
-// the helper to be exercised against a real Postgres before the PR
