New: Program Access Modes — Public, Private & Invite-Only

Replace the old auto-approve toggle with three clear options:

• Public — Anyone can sign up and is automatically approved
• Private — Anyone can apply, but you approve each affiliate manually
• Invite-Only — Only affiliates you explicitly invite can join

We also made several portal improvements:

• New Three access modes for granular program enrollment control
• Improved Disabled affiliate links are now hidden in the portal instead of shown as inactive
• Improved Onboarding adapts automatically when affiliate links are disabled
• Fixed Missing European countries added to the invoice address dropdown
• Fixed Notification labels corrected and translated to English
