Add attestation_due_bps_gloas and payload_attestation_due_bps to ChainSpec

Browse Source 
Spec: `get_attestation_due_ms(epoch)` uses ATTESTATION_DUE_BPS_GLOAS
(2500) for Gloas epochs vs ATTESTATION_DUE_BPS (3333) pre-Gloas.
`get_payload_attestation_due_ms` uses PAYLOAD_ATTESTATION_DUE_BPS (7500).

- Add both BPS fields to ChainSpec with derived Duration values
- Add `get_attestation_due::<E>(slot)` that returns epoch-appropriate
  threshold matching the spec
- Add `get_payload_attestation_due()` matching the spec
- Use them in proto_array record_block_timeliness instead of hardcoded
  values
