fix(svelte-table): Don't directly reference local state (#5943)

In svelte 5, $state referenced locally is not reactive, because of how evaluation occurs.

Svelte will warn about this at runtime (and does so here)
To make it reactive locally, we use property getters, to ensure we always return the latest state.
