gui(vdigit): Fix for Wrong number of arguments in a call of stub class

[echoix]

If we look at the stub class created as a fallback just above in that small file, we clearly see that calling __init__ with more arguments than the stub won’t work. So add the extra arguments.

---

Generated PR text:
To fix this without changing behavior, make the fallback IVDigit constructor accept the same arguments as the primary implementation usage in VDigit.__init__.

Best single fix:

• File: gui/wxpython/vdigit/main.py
• Region: fallback class in the except block (lines 27–29 in snippet)
• Change:
  • from def __init__(self):
  • to def __init__(self, giface, mapwindow):
• Keep body as pass (stub behavior unchanged).
• No new imports or dependencies are needed.

This preserves existing functionality while removing the argument-count runtime hazard and satisfying the static analysis rule.
