Subject: [PATCH] feat: Implement real-time trading notifications

Adds a `NotificationManager` component to the application that listens for new trading signals from Firestore. When a new signal is detected, it requests notification permission from the user and displays a browser notification if permission is granted.

This change enhances user experience by providing immediate alerts for potential trading opportunities.

Also includes minor UI and styling adjustments in `AnalysisView` and `LandingPage` for improved clarity and consistency.
