Every current vector carries an empty gov/cert state, so this is effectively the same as passing Default::defualt. However, this removes a future foot-gun if someone were to change the test vectors.

The phase-2 script-context evaluation in the mempool built pallas'
`SlotConfig` directly from `ChainSummary`, which keeps `slot_length` and
`timestamp` in seconds (the Ouroboros era-summary convention). Pallas'
`SlotConfig` expects milliseconds and performs no scaling of its own
(`zero_time + (slot - zero_slot) * slot_length`), so the resulting
`POSIXTime` in `txInfoValidRange` was 1000x too small. Scripts that
inspect the validity range (deadlines, time-locks) would mis-validate.

Centralize the seconds->milliseconds conversion in a new
`ChainSummary::to_pallas_slot_config()` helper and use it from
`evaluate_tx`. This mirrors the existing gRPC era-summary boundary, which
already multiplies `timestamp` by 1000 on output.
