Fix managed_account QR exclusion and bare except in action_bar

- Remove 'qr' from managed_account context actions (accounts don't expose
  a QR-scannable key like seeds/nostr do)
- Change bare 'except:' to 'except Exception:' on vault manager check
- Add test_v3_action_bar_managed_account_excludes_qr in parity tests
