improvement(app): show branded wordmark while loading

[waleedlatif1]

Summary

• Show the canonical muted Sim wordmark while the application shell loads, using the existing light and dark theme tokens without adding animation or a minimum delay.
• Replace the workspace entry and workflow navigation spinners with the same loading surface. Preserve desktop title-bar dragging, custom branding, and existing error and empty states.
• Start workspace data and authorized branding reads in parallel; show the correctly branded loading screen while retaining the shared query cache and provider hierarchy.

Type of Change

• Improvement

Testing

• Real local app and disposable PostgreSQL: hard refresh in light/dark themes, centered geometry, loading-to-ready transition, and subsequent Files navigation. Screenshots and JSON reports captured.
• HTTP streaming checks held sidebar reads in a database transaction: both Sim and custom-branded workspaces showed their loading surface before data was released. Signed-out and denied-workspace paths retained their existing behavior. Removing the fallback made the streaming checks fail; restoring it passed.
• Delayed-read HTTP verification reproduced serialized branding/sidebar reads before the review fix and concurrent starts after it. Custom branding, loading-to-ready completion, and access checks passed.
• Existing layout tests updated to await streaming completion; 13 adjacent tests passed. Full root tests, all 26 workspace type checks, 58 audits, lint, generators, block registry, docs manifest, and pinned actionlint passed.

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing (new tests pass the test-audit authoring gate)
• No new warnings introduced
• I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)
