Title: VaultT4Oracle

Per-vault oracle for T4 vaults (smart collateral + smart debt). Supports both same-pool and different-pool T4 vaults by always storing separate col and debt DEX params. When supply == borrow, immutables are simply duplicated (negligible extra cost: ~24 gas from 8 extra PUSHes).
