fix: cleanup-duplicate-prs.sh — fix AUTH bug, add stale branch cleanup (#1453)

Bug fix:
- Line 38: AUTH variable was corrupted ('***'), now correctly reads
  'Authorization: token '

New feature: stale branch cleanup
- Added cleanup of branches from closed (unmerged) PRs
- Added cleanup of branches from merged PRs (where auto-delete failed)
- Both respect --dry-run / --close mode

Actual cleanup performed:
- Deleted whip/1127-1776128804 (closed PR #1409)
- Deleted whip/1127-1776127532 (merged PR #1403)
Both were stale branches from the duplicate #1127 PRs.
