Widget width not matching expected result on larger screen sizes

[detectity-revs]

Bug description

The widget width value at the 50% option does not match expectations when viewed at larger screen sizes. When set to 'width' => 50 in the configuration, it will instead show at 33% width rather than 50% width.

I've identified the source of the issue is defined in cms/resources/js/pages/Dashboard.vue, where @7xl:w-1/3 is set instead of @7xl:w-1/2. Manually changing this in the web inspector tools corrects the problem.

How to reproduce

1. Create two collections named example_1 and example_2, or use two existing collections
2. Define dashboard widgets in config/statamic/cp.php to the above collections:

'widgets' => [
    [
        'type' => 'collection',
        'collection' => 'example_1',
        'width' => 50,
    ],
    [
        'type' => 'collection',
        'collection' => 'example_2',
        'width' => 50,
    ],
],

3. Navigate to the dashboard page
4. Enlarge screen size to at least 1554px wide
5. Observe error with width of widgets being shown at 33% instead of 50%

This is a consequence of #13910 (comment). The PR fixed an issue where the new sm size never dropped down to 1/4 width, but also makes the translation from old numbers-based sizes to new abstract size names less predictable since they don't transfer directly.

That said, I'd vote for allowing both: the new dynamic system as well as the old reliable numbers for better control.
