Setup GitHub Workflow for OpenAPI/Swagger Client Generation

[jimmypalelil]

Description

Create a GitHub workflow to automatically generate and update the client SDK from our NestJS Swagger implementation for the backend server app. This will ensure the client code stays in sync with our API changes.

Acceptance Criteria

• Create a GitHub Actions workflow file that triggers on push and pull requests
• Implement steps to auto generate client SDK using openapi-generator-cli
• Add validation steps to ensure generated client is committed and up-to-date
• Document the workflow process in the repository README
• Setup pre-commit hooks for local development to check client generation

Additional context

• Research and implement husky for pre-commit hooks
• Consider adding validation steps to prevent commits if client is out of sync
• Document local setup process for developers

Technical Requirements

• GitHub Actions workflow configuration
• Local development tools (e.g: husky)
• Client generation scripts and configuration
