 a111de1ece Security hardening: fix all 8 blocking findings for PR #419 
Fix 1: Update support.js to collect SSH public key and POST JSON
Fix 2: Legacy njalla.sh migration - parse safely, archive non-executable, replace cron with systemd timer
Fix 3: DDNS SSRF prevention - allowlist only njal.la, reject other hosts, disable curl redirects
Fix 4: Legacy root support-key removal migration (_remove_legacy_root_support_key)
Fix 5: Automatic support-key expiration (expires_at + _expire_support_if_stale)
Fix 6: Move security helpers to security_helpers.py, tests import production code
Fix 7: Real NIP-19/Bech32 npub validation (_bech32_decode + _validate_npub)
Fix 8: Replace journalctl sudo wildcard with restricted sovran-journal-helper.py
Also: Make _write_hub_overrides() atomic with tempfile+os.replace
94 tests passing

"""Security regression tests for Sovran Hub security helpers.
Tests exercise the exact production implementations imported from

redefined here. Every test verifies the deployed code, not a copy.
Tests must never:
- reboot, rebuild, or alter real SSH keys
