refactor: extract duplicate validator axon collection to shared helper

[dataCenter430]

The same 5-line loop — iterating over metagraph.n to collect axons and UIDs for validators with vtrust > 0.1 — was copy-pasted across both post.py and check.py. Extracting it as _get_validator_axons(metagraph) in post.py means check.py (which already imports helpers from post.py) can simply call the shared function.

• Pyright clean
• Ruff lint and format clean

Looks good — clean dedup, follows the existing issue_commands/helpers.py pattern.

Minor note: check.py still imports _error, _load_config_value, _resolve_endpoint, and NETUID_DEFAULT from post.py as shared helpers. If more helpers get extracted in the future, consider moving those into helpers.py too so shared utilities live in one place.

May I open a follow-up PR for it or implement it on this PR?
