chore: remove decommissioned feedback.profullstack.com widget

[ralyodio]

The Profullstack feedback widget (feedback.profullstack.com) has been decommissioned.

This removes every trace:

• FeedbackWidget embed + import from apps/web/src/app/layout.tsx
• https://feedback.profullstack.com from the script-src CSP directive in apps/web/src/middleware.ts
• stale comment mentions of the feedback widget
