feat: wire trust score system with cross-chain staking data and component triggers

- Add CachedStakingDetails storage and receive_staking_details extrinsic
  to staking-score pallet for Asset Hub XCM data reception
- Add TrustScoreUpdater triggers to referral, tiki, and perwerde pallets
  so component score changes propagate to trust pallet
- Wire runtime hooks (OnKycApproved, OnCitizenshipRevoked) to Referral
  and CitizenNftProvider to Tiki in people.rs
- Fix PerwerdeScoreSource and ReferralScoreSource to read actual pallet data
- Fix EnsureOrigin trait feature unification issue by removing cfg gate
  from try_successful_origin and adding default Err(()) implementation
- Fix workspace Cargo.toml default-features for pezkuwi-subxt dependencies
