feat: add is_local() function to detect Supabase CLI environment

[jumski]

Add pgflow.is_local() function to detect local development environment

This PR adds a new SQL function pgflow.is_local() that detects whether the application is running in a local Supabase CLI environment by checking if the JWT secret matches the known hardcoded local value.

The function:

• Returns true only when the JWT secret exactly matches the Supabase CLI's default value
• Returns false in all other cases (production environments, custom JWT secrets)
• Is designed to be production-safe with a default of false
• Uses coalesce to handle missing configuration values

Added comprehensive tests to verify the function works correctly in different scenarios:

• When JWT secret matches the local Supabase value
• When JWT secret is empty/missing (simulates hosted environments)
• When JWT secret has a different custom value

This utility will help implement environment-specific behaviors without requiring explicit configuration.
