Fix connection form: guard against undefined user/pass + add Edit menu for CMD+A/C/V

- textfieldGetString returns undefined for untouched fields; encodeURIComponent(undefined)
  produced "undefined" in the URI. Now check encoded result for "undef" before including auth.
- Add Edit menu with standard macOS actions (Undo/Redo/Cut/Copy/Paste/Select All) via
  menuAddStandardAction so keyboard shortcuts work in text fields.
- Add Tab navigation between connection form fields via textfieldSetNextKeyView.
