refactor: inline single-use _single_paragraph and _get_contract_info_value helpers

[ebios-star]

Summary

Folded #819 into this PR per @anderdc's review. Two single-use module-level helpers inlined into their only callers:

1. _single_paragraph in gittensor/cli/issue_commands/help.py — 3-line wrapper around ' '.join(text.split()), called only from StyledGroup.get_help. Inlined idiom is conventional Python for collapsing whitespace.

2. _get_contract_info_value in gittensor/validator/issue_competitions/storage_utils.py — 3-line wrapper around contract_info.value if hasattr(contract_info, 'value') else contract_info, called only from _extract_trie_id_bytes. The hasattr fallback is preserved verbatim so all three substrate trie_id shapes (str/bytes/list) covered by test_get_contract_child_storage_key_accepts_multiple_trie_id_formats still resolve identically.

grep -rn confirms a single call site for each helper, no test references.

Net: -12 / +2 lines combined, two fewer private helpers.

@anderdc @LandynDev — friendly ping for review when you have a moment.

Same family as #748 (merged) and #641. _single_paragraph was a 3-line wrapper around ' '.join(text.split()) called from one place; the inlined idiom reads as cleanly. grep confirms a single call site, no test references. -6/+1 lines, full test suite passes.

Happy to rebase if needed.

Fold your #819 changes into this. No need to have had them separated

Fold all your inline PRs into this one. no need to separate them.

Done @anderdc — folded #819 into this PR.

Branch is now rebased onto current test and contains two commits: the original _single_paragraph inline plus the cherry-picked _get_contract_info_value inline. Title and description updated to cover both. Force-pushed with --force-with-lease. All 652 tests pass.

Happy to squash to a single commit if you'd prefer that shape.

Hi @anderdc — thanks for the quick review and clear direction on the consolidation. The requested fold is in: this PR now contains both inline-helper commits, rebased onto current test, with the description updated to cover both. CI is green on my end (652/652).

Whenever you have a moment for a re-review, I'd really appreciate it. Happy to address any further feedback or squash to a single commit if that shape works better for you.
