fix(network): clear ENR nfd field when no next fork is scheduled during runtime transitions (#9131)

No. But related to #9009 and #8996


  - Change the `ForkContext::next_fork_digest()` to return `[u8; 4]` (returning `[0u8; 4]` for "no next fork").
- Update the initialization path and runtime fork transition path accordingly.

Added tests:
- [x] `test_next_fork_digest` — existing test passes with non-Option return type
- [x] `test_next_fork_digest_returns_zero_when_no_next_fork` — init at last BPO fork returns `[0u8; 4]`
- [x] `test_next_fork_digest_zero_after_runtime_transition_to_last_fork` — simulates `update_current_fork` to last fork, then verifies zero
