[Bug]: DimensionGrid doesn't SSR data

[csjh]

Describe the bug

DimensionGrid needs to be cleaned up a bit for it to be compatible with SSR data (which should fix its double loading issues)

One fundamental problem is that it is not guaranteed to have a unique, reproducible identifier (the name prop is optional because it isn't always used as an input) - waiting for sveltejs/svelte#7517 would help here if we're fine with holding off on this fix

Steps to Reproduce

use DimensionGrid, build site, view site

ex: https://sf311.evidence.app via https://github.com/evidence-dev/sf311

Severity

annoyance
