Fix MND reward display

[aledefra]

Summary

• update the Explorer MND ABI to match the deployed reward parameter shape
• pack oracle availability values into packedAvailabilities and pass fromEpoch / toEpoch to calculateRewards
• keep the existing undefined fallback when oracle epochs are incomplete or non-contiguous

Root Cause

MND rewards were rendered as ... because the Explorer still called calculateRewards with the old { epochs, availabilies } tuple. The deployed MND contract expects { fromEpoch, toEpoch, packedAvailabilities }, so the read reverted and the UI treated the reward as unavailable.

Validation

• npm run lint
• npm run build
• local runtime check for /license/MND/17 rendered Rewards (PoA) as 55 $R1 with 9.94 carryover instead of ...

Note: npm run build still logs existing stats-page upstream transfer JSON warnings (Must be au...) during static generation, but the build exits successfully.

Pull request overview

This PR fixes MND reward rendering in the Explorer by aligning the calculateRewards call with the deployed MND contract’s updated parameter shape (epoch range + packed availability bytes), preventing the contract read from reverting and the UI from falling back to ....

Changes:

• Update the Explorer’s MND ABI calculateRewards tuple fields from { epochs, availabilies } to { fromEpoch, toEpoch, packedAvailabilities }.
• Add validation that oracle epoch data is complete and contiguous, then pack epochs_vals into a bytes hex payload.
• Pass fromEpoch / toEpoch along with packedAvailabilities into calculateRewards.
