Pull Request Overview

This PR standardizes error handling in the supervisor module by consolidating similar error types and improving naming consistency. The changes aim to resolve issue #2278 by reducing redundancy in error definitions and making the error system more maintainable.

• Removes redundant error variants (InvalidAnchor, DerivedBlockOutOfOrder) and consolidates them into existing generic variants
• Renames function parameters from anchor to activation_block/activation_pair for clarity
• Updates all references and test cases to use the consolidated error types
