Feature/node 4923 refactor upgrade tests to use local configurations

[GTC6244]

Pull request overview

This pull request refactors upgrade tests to use local configurations instead of remote branch-based testing. The key changes include:

• Simplified upgrade testing approach using local release binaries instead of fetching builds from remote branches
• Method renaming for consistency: get_validator_by_idx → get_validator_by_index and get_validator_by_idx_mut → get_validator_by_index_as_mut
• Extraction of invalid version tests into a separate module
• Addition of temporary backward compatibility code for DKG ID generation to support upgrade from version 2.1.5 to 2.1.6+
• Contract schema updates to add a deprecated key_types_deprecated field to GlobalConfig
• Implementation of Clone traits for test infrastructure types

NOTES:

• the network checker functionality is disabled at the moment. There seems to be some discrepancy in signing ( though not encryption ! ) that happens while the nodes are at different versions.
• a final check shows that the upgraded network does work, though.
• If time permits we can investigate this interim state ( appears to be related to the generation of presigs 😦 )
