refactor(auth): drop the 14 unreachable commenter-auth catch wrappers

[mrbobbytables]

Description

checkOrgMember, checkCollaborator and checkIssueComments (src/utils/auth.ts) each wrap their whole body in try { … } catch { core.warning(…); return false }, so they never reject. The fourteen try { … } catch (e) { throw new Error('could not check … auth: ' + e) } wrappers around them were therefore unreachable from the shipped bundle and were kept green only by unit tests that vi.mocked the callee to reject (or made core.warning throw) — pinning error messages the action can never emit, including the misspelt couldn ot check commentor Auth.

This PR removes them, as recommended in #386:

• close.ts, reopen.ts, lock.ts, milestone.ts, retitle.ts, unassign.ts, labels/remove.ts: call the probe directly (close/reopen become a single isAuthor || collaborator || closePolicyAllows short-circuit chain, same evaluation order as before)
• assign.ts, cc.ts, uncc.ts: drop the could not get authorized users wrappers
• auth.ts: drop the wrapper in getOrgCollabCommentUsers and the three in checkCommenterAuth; getOrgCollabCommentUsers now reuses checkCommenterAuth per user (same three probes in the same order, so identical API traffic). Also fixes the @param args → user jsdoc mismatch on checkCommenterAuth that npm run lint warned about.
• Delete the 15 mock-only unit cases (__tests__/issueCommentTest/errorPaths.test.ts ×8, approveMilestoneErrorPaths.test.ts ×1, __tests__/label/errorPaths.test.ts ×1, __tests__/utils/auth.test.ts ×4 logger down) and reword the vi.mock lead-in comments that described the removed branches. The mocks themselves stay — the remaining cases still use mockResolvedValueOnce.
• dist/index.js repacked.

No behaviour change: every removed catch was dead, and every probe call sequence is unchanged.

Fixes #386

Testing

• npm run all — build, lint:fix, lint, pack, test: 151 files / 2075 tests pass; lint has 0 errors (1 pre-existing jsdoc warning in src/issueComment/cc.ts:81, not touched here)
• npm run test:coverage — 100 % lines / 99.7 % branches / 100 % functions / 100 % statements, so every line in the touched files is still reached by the unit suite without the deleted mock-rejection cases
• npm run test:coverage:e2e — 72 files / 452 tests pass; src/ e2e lines 98.73 % → 99.28 %; the only remaining 0-hit line in the touched files is the unrelated auth.ts:24

Checklist

• I ran npm run all to lint and build my code
• I ran npm run pack and committed dist/
• Commits are signed off (DCO)
• Note any new dependencies these changes bring in — none
• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas — nothing non-obvious added; the removed code had the comments
• I have made corresponding changes to the documentation — none needed (no user-facing behaviour or docs reference the removed messages)
• My changes generates no new warnings (please describe new warnings if unavoidable) — removes one lint warning, adds none

⚠️ Sentinel alert — maintainer review required

Hive flagged this PR (author @mrbobbytables, head 9e11e3a9b6b2) because it matches behaviors that can override security controls, escalate privileges or damage the codebase. This is a heuristic, not an accusation — a maintainer should confirm the change is intended before it merges.

• test_removal — removes 136 test lines while adding 6 (Deletes test files or guts test coverage)
  • __tests__/issueCommentTest/approveMilestoneErrorPaths.test.ts
  • __tests__/issueCommentTest/errorPaths.test.ts
  • __tests__/label/errorPaths.test.ts
  • __tests__/utils/auth.test.ts

Hive added the sentinel-alert label. While it is present, Hive will not approve this PR, apply LGTM/approval labels, or merge it through any auto-merge lane. Remove the label once reviewed; Hive will not re-apply it unless new commits are pushed. Tune paths and behaviors under sentinel in hive.yaml or the dashboard Security tab.
