fix(web): preserve authenticated navigation destinations

[AmzBG]

Description

• Preserve the requested protected destination after login by performing a full browser navigation once authentication succeeds.
• Open draft project previews in the current authenticated tab instead of a new tab.
• Prevent project preview navigation from unexpectedly landing on the dashboard.

Steps to QA

1. Log out of the application.

2. Open a published project.

3. Select a linked developer profile.

4. Confirm the application redirects to login because developer profiles are protected.

5. Log in and confirm the browser continues to the originally requested developer profile.

6. Open an owned draft project for editing.

7. Select Preview.

8. Confirm the preview opens in the current tab at /projects/preview/<project-id>.

9. Confirm the draft preview renders using the public-project presentation without redirecting to the dashboard.

10. Run the automated checks:

    npx turbo run lint
    npx turbo run check-types
    npm run format:check
    npx turbo run build --filter=web
