Update tab title and favicon for branding consistency

[Pooja675]

Description:

In the browser tab, the title currently shows “CareerCrack” and the favicon is still the default one. This causes inconsistency with the application branding (EDGEx AI Toolkit).

Screenshot

Expected Behavior:

• The browser tab title should display “EDGEx AI Toolkit”.
• The favicon should be updated to the official EDGEx logo for consistent branding.
