Pull Request Overview

This PR primarily updates the Subtensor pallets and related tests to use the unsigned fixed‐point type U96F32 in place of I96F32, along with several related type conversions and new features for migrations and runtime APIs. Key changes include:

• Replacing I96F32 with U96F32 (and similar adjustments for other fixed-point types) in staking, coinbase, commitments, and helper modules.
• Adding a new migration module (migrate_upgrade_revealed_commitments) and extending the runtime API with get_selective_metagraph.
• Updating EVM test contracts and configurations to align with the aforementioned changes.

• The conversion from U96F32 results (used in prior calculations) to I96F32 here may introduce precision or range issues. Consider maintaining a consistent fixed-point type for moving price values or thoroughly document why the conversion to a signed type is necessary.

let new_moving: I96F32 = I96F32::saturating_from_num(current_price.saturating_add(current_moving));

• [nitpick] Enforcing a maximum of 10 revealed entries by draining older items might lead to loss of potentially useful historical data. Confirm that this limit meets the application requirements or consider making the cap configurable.

• [nitpick] Ensure the error message for the get_selective_metagraph RPC call provides enough context for debugging while not exposing sensitive internal details.

Err(e) => Err(Error::RuntimeError(format!("Unable to get selective metagraph: {:?}", e)).into()),
