Update health timestamps in EoaExecutorWorker and ResetNoncesTransaction (#70)

- Added logic to update health timestamps for nonce movement and confirmations in both the EoaExecutorWorker and ResetNoncesTransaction implementations.
- Ensured health data reflects the latest nonce movement even when confirmations are ahead of the latest state.
