refactor(pxe): restore satisfies-typed oracle registries

[nchamo]

Summary

• refactor(sequencer)!: always enforce timetable with concrete block duration #23821 (a sequencer-timetable refactor) incidentally rewrote the oracle registry typings: it swapped the satisfies Record<string, OracleRegistryEntry> form on ORACLE_REGISTRY and TXE_ORACLE_REGISTRY for explicit Record<…> / hand-maintained named-union annotations, widened the test resolver's fixtures parameter to Partial<…>, and added an explicit return type on getLastTxEffects.
• Those annotations widen every registry entry to the generic OracleRegistryEntry, which collapses the derived oracle interfaces (IMiscOracle / IUtilityExecutionOracle / IPrivateExecutionOracle) and the TXE roundtrip-test fixture types (OracleTestScenario<K>) down to any / string, silently dropping the per-oracle type checking that refactor(pxe)!: derive oracle interfaces from registry and introduce aztec_misc_ prefix #23840 and the oracle test framework were built to provide.
• This reverts those four type-level edits back to the satisfies form, restoring the precise per-entry types. tsgo declaration build, --noEmit, and lint all pass on pxe and txe.
