Update blocked IP handling to use custom blocked page with 403 status

**Template Changes:**
- Switch from direct denial to blocked page redirect with 403 status
- Blocked IPs now see /blocked-ip page instead of generic 403 denial
- Maintains proper 403 HTTP status code for blocked requests

**Blocked Page Updates:**
- Remove contact support button to prevent misuse
- Add clear instructions on how to request unblocking
- Provide structured guidance for contacting hosting provider
- Maintain professional appearance with helpful information

**Benefits:**
- Better user experience for legitimate blocks
- Clear instructions prevent support confusion
- Maintains security while being informative
- Professional appearance reflects well on hosting providers
