API Key Access & Subscription Tier Fix

🔧 What's Improved

API Key Tab Access

The API key management tab in Settings was blocked for accounts that were manually upgraded from Free to Base tier. The issue was that manual_override was not set to true during the tier change, causing the subscription validation to fail.

Fix: Set manual_override = true for affected accounts and updated the tier change trigger to automatically set this flag when no Stripe subscription is present.

How It Works Now

• Accounts on Base or Premium plans can always access the API key tab
• Manual tier overrides are properly tracked
• The subscription tier change trigger handles all edge cases consistently
