Grid.new fails if 1D array provided

Description of Bug

If trying to create a grid for a 2D metric by providing a 1D array of ticks, it fails validation.

Steps To Reproduce

Code to reproduce the behavior:

import simvue
import numpy

with simvue.Run() as run:
    run.init("test")
    run.assign_metric_to_grid(metric_name="test_metric_2d", axes_ticks=numpy.arange(10), axes_labels=['x'])
    for i in range(10):
        run.log_metrics({"test_metric_2d": numpy.random.rand(10)}, time=i, step=i)

Expected behavior

Grid added correctly

Actual Behaviour

Setup

• OS: [e.g. Windows 11]
• Python version [e.g. v3.13.3]

Additional context

Add any other context about the problem here.

Start with the assign_metric_to_grid call in simvue/run.py and the validation wrappers in simvue/utilities.py, then reproduce the failure using the provided NumPy example. Check how Grid.new validates the grid input. Done means a 1D axes_ticks array with a single label creates the grid successfully without the reported validation error.
