FE 2 - Implement forgot password page fully

[notjackl3]

Create the forgot password page with UI and API integration. Here are some resources:

• Figma design
• How to create React components

Notes:

• Follow existing Figma design
• Include a description of the ticket and the implementation in the PR (with screenshots showing success and error states!)
• Only allow admins to request the forgot password

The goal is to:

• Create page layout matching the design with header navigation
• Include email input field with validation (only allow admin emails)
• Display instructional text as per the design
• Connect to password reset API endpoint
• Show success message after email is sent
• Handle and display errors appropriately
