refactor(scores): remove frontend fallback, read all scores from blockchain

Remove all frontend staking/trust score calculation and localStorage
fallback code. All scores now read directly from People Chain pallets
(pezpallet-trust, pezpallet-referral, pezpallet-tiki). Trust pallet
computes composite score on-chain.
