Pull Request Overview
This PR implements the v1.2.0 migration for uniond which introduces a new U token and removes POA (Proof of Authority) functionality. The migration mints the total supply of U tokens, undelegates existing delegations, burns old tokens, and updates all module parameters to use the new token denomination.
Key changes:
- Implements comprehensive v1.2.0 upgrade handler that mints U tokens and burns legacy tokens
- Removes POA module dependencies and references throughout the codebase
- Updates module parameters across staking, mint, gov, crisis, distribution, and feemarket modules to use new U token
