Add Domain Redirect Feature

[nguyentranchung]

We plan to add a Domain Redirect feature to FlashPanel. This will allow users to redirect subdomains or additional domains to the primary domain easily.

Key Features:
• Redirect any subdomain (e.g., blog.example.com) to the main domain (example.com).
• Support for both temporary (302) and permanent (301) redirects.
• Option to redirect with or without path forwarding.
• Simple UI in the panel to manage redirects.

Use Case:
Users who own multiple domains or subdomains can automatically forward traffic to a single primary domain, improving SEO and avoiding duplicate content issues.
