feat(overlord): add async script to set vote vp value

[wa0x6e]

In continuation to #567

This PR will add a new async script, which will periodically update votes' vp_value when necessary.

Flow

• the script will fetch all votes with cb PENDING_COMPUTE (default value on vote creation), and compute a new vp_value, when the proposal vp_value_by_strategy is ready, as well as assign a new CB (FINAL when the vp_state is final, PENDING_FINAL otherwise)
• When a new votes with overriding strategy is added, all the votes will be set to PENDING_COMPUTE
• Those votes will be picked by the script again, and back to step 1

Pull Request Overview

This PR adds asynchronous scripts to periodically update vote values based on proposal strategy values. It introduces new voting power value computation logic that relies on an external Overlord service and implements a multi-stage callback state system for managing value synchronization.

• Adds new helper modules for refreshing proposal strategy values and vote VP values
• Refactors vote value calculation to use separate array parameters instead of full objects
• Introduces callback state constants and removes immediate VP value computation during vote creation
