Fix Backend Deployment on Render

Issues Resolved

Python Version Conflicts: Fixed incompatibility between Python 3.13 and pandas 2.1.4 by standardising on Python 3.11 across all configurations.

Missing Dependencies: Added supabase package to requirements.txt which was imported in code but not declared as a dependency.

Pydantic Version Conflicts: Updated pydantic from 2.5.3 to 2.11.7 to resolve conflicts with supabase realtime package dependencies.

PORT Configuration: Removed incorrect PORT environment variable configuration that was generating random strings instead of port numbers.

Changes Made

• Updated backend/requirements.txt with supabase and upgraded pydantic
• Configured Python 3.11 via .python-version file
• Cleaned up render.yaml environment variables
• Removed sensitive credentials from version control

Result

Backend now deploys successfully on Render without dependency conflicts or configuration errors.

Summary by CodeRabbit

• Chores
  • Upgraded a backend dependency (pydantic) to a newer version to keep the platform current.
  • Improves overall stability and compatibility with recent tooling.
  • No user-facing behavior changes are expected.

Poem

I nudge the numbers, hop and twirl,
A version rises—give it a whirl!
Carrots counted, deps aligned,
Fewer bugs for peace of mind.
Thump-thump, ship it—swift and bright! 🥕✨
