chore: add Supabase keepalive endpoint and schedule cron job

[DongDuong2001]

This pull request introduces a scheduled health check endpoint for Supabase and configures a Vercel cron job to periodically invoke it. The main goal is to ensure the Supabase connection remains active and to monitor its health.

Supabase keepalive endpoint:

• Added a new API route app/api/cron/supabase-keepalive/route.ts that performs an authenticated health check on the Supabase profiles table, returning latency and row count information; it responds with an error if the check fails or if authorization is invalid.

Cron job configuration:

• Updated vercel.json to schedule a daily (3:00 AM UTC) cron job that triggers the new /api/cron/supabase-keepalive endpoint, ensuring regular health checks.

• Chores
  • Added a new scheduled daily background task for backend infrastructure.

📝 Walkthrough

Walkthrough

This PR adds a Supabase health check cron job. A new Next.js API route authenticates requests, creates a Supabase admin client, queries the profiles table, measures latency, and returns status. Vercel's cron configuration is updated to trigger this endpoint daily at 03:00 UTC.

Poem

🐰 A hop through the database each morning dawn,
Our health check bounces till the night is gone,
From Supabase whispers, latency we measure,
Every three o'clock brings a cron's sweet pleasure! ✨
