Filter format inconsistent with UI

Description of Bug

When you copy a filter with multiple different items from the UI, you get:
"folder.path == /GS2/test_data && metrics.mtm.last == 1"

But if you submit that via the Client class, you get an error:

RuntimeError: Retrieval of runs failed for url 'https://uk.simvue.io/api/runs?filters=%5B%22folder.path+%3D%3D+%2FGS2%2Ftest_data+%26%26+metrics.mtm.last+%3D%3D+1%22%5D&return_basic=True&return_metrics=True&return_alerts=False&return_system=False&return_metadata=True&count=100&start=0' with status 422: Invalid filter

We believe this is because the python API instead expects a list of filters, not '&&'. Could we fix it so that the python API accepts either format and converts it appropriately?

Steps To Reproduce

Steps to reproduce the behavior:

1. Go to web UI
2. Add two filters
3. Copy filter string with the button on the UI, and paste into client.get_runs()
4. See error

Expected behavior

Runs retrieved correctly

Actual Behaviour

422 error

Setup

• OS: Ubuntu
• Python version: 3.10

Additional context

Add any other context about the problem here.

Comienza en el punto de entrada Client.get_runs() mencionado en la reproducción y sigue cómo se formatea su argumento de filtro para la solicitud de runs. Reproduce el ejemplo de dos filtros del issue y, después, verifica que tanto la cadena && de la UI como el formato de lista existente recuperen runs sin un error 422.
