dapplion 2cfe5ff380 Fix get_validator_duties_early after #8415 merge

PR #8415 added Gloas-only payload-timeliness-committee assertions to
test_get_validator_duties_early but kept the test using
ApiTester::new() (default mainnet spec). With FORK_NAME=gloas this
produces a phase0 chain, so post_validator_duties_ptc returns 500
with BeaconStateError(IncorrectStateVariant).

Two issues fixed:

1. Switch the test wrapper to ApiTester::new_with_hard_forks() so the
   chain is actually at Gloas under FORK_NAME=gloas. This is the same
   pattern already used by get_validator_duties_ptc and
   get_validator_payload_attestation_data.

2. Compute dependent_root using
   ChainSpec::proposer_shuffling_decision_slot rather than the
   hardcoded "(current_epoch - 1).end_slot()" formula. Post-Fulu the
   proposer shuffling decision slot moved to the end of epoch N - 2,
   so the cache is now keyed by that root. The old formula matched
   the legacy cache key and silently passed on phase0 chains.

Verified locally with FORK_NAME=gloas (195/195) and FORK_NAME=fulu
(195/195).
