Subtensor v477 fixes root claims on testnet and node log display

This release fixes a testnet issue where claiming Root rewards for a single Hotkey was rejected because of an oversized resource reservation. Mainnet behavior is unchanged. Node logs also display sync and block-import messages correctly.

Testnet Root claims no longer rejected for oversized weight

On testnet, claiming Root rewards for a single Hotkey could fail validation even with an empty Basket, because the transaction reserved more resources than a normal transaction allows. The reservation is restored to the smaller single-Hotkey size. Mainnet is unchanged, and Baskets with more than 128 holding rows remain too heavy to claim.

Source #3219

Other changes

Node logs no longer show raw color codes in sync and block-import messages, and the runtime version and Python package versions were bumped.
