Align pivot table text left

[ericokuma]

Fixes APP-575

Ensures that wrapped text for Measures, Dimensions, and Time chips in the pivot table sidebar is left-aligned. Previously, these chips were center-aligned, leading to an awkward appearance when text wrapped.

This is achieved by:

1. Setting fullWidth to true for chips in the "Time", "Measures", and "Dimensions" zones within the DragList.svelte.
2. Updating the Chip.svelte styles to apply justify-start and text-left for any chip with the fullWidth class.
