feat: add flow compilation utilities for creating flows from JSON shapes

[jumski]

Add Flow Compilation and Deletion Utilities

This PR adds two new utility functions to help with flow management:

1. pgflow._create_flow_from_shape(p_flow_slug, p_shape) - Creates a complete flow from a JSONB shape definition, handling steps and dependencies in a single operation.

2. pgflow.delete_flow_and_data(p_flow_slug) - Safely removes a flow and all its associated runtime data, including PGMQ queues and all database records.

The implementation includes:

• Schema definitions for both functions
• Supabase migration to deploy the functions
• Comprehensive test coverage for both functions, including:
  • Basic flow compilation
  • Map step compilation
  • Flow definition deletion
  • Runtime data deletion

These utilities will be particularly useful for development mode recompilation and for managing flows programmatically.
