Add safe SerpApi backup key failover

[hoangsvit]

Summary

• support up to 3 configured SerpApi secrets
• use backup keys only when the current key fails for a non-quota reason
• stop immediately on quota/rate-limit responses instead of switching credentials
• keep the existing flight tracking schedule and price alert flow unchanged

Secrets

Configure any of these in Settings → Secrets and variables → Actions:

• SERPAPI_API_KEY
• SERPAPI_API_KEY_2
• SERPAPI_API_KEY_3

The workflow prefers the first configured key and only falls back when a key is invalid/revoked or a transient non-quota error occurs.
