feat: add constraints for input patterns and improve cascade skip tests

[jumski]

Add constraints and improve cascade skip functionality

This PR adds database constraints to ensure required_input_pattern and forbidden_input_pattern are always JSON objects, preventing invalid pattern types. It also enhances the _cascade_force_skip_steps function to:

1. Return the count of skipped steps
2. Make the function idempotent (safe to call multiple times)
3. Improve event ordering tests with a more reliable trigger-based approach

The changes include:

• Added CHECK constraints to the steps table to validate pattern types
• Made _cascade_force_skip_steps return the number of steps skipped
• Added a new test for idempotent behavior of _cascade_force_skip_steps
• Improved event ordering tests to use a trigger-based approach instead of timestamp ordering
• Added tests to verify rejection of invalid pattern types (arrays, strings)
• Enhanced flow shape comparison tests to detect pattern differences

These changes improve data integrity and make the cascade skip functionality more robust and predictable.
