Audit and review structural improvements across Skeleton utility classes

[endigo9740]

Goal

The focus of this audit will be to determine which Tailwind Components and other Skeleton-specific utility classes are in need of updates.

Elements To Update

• Explore breaking the HTML table styles into smaller parts (.tbody, .thead, .td, etc). A composed model essentially.
• Update .code to allow for Presets; provide a solution for legacy support
• Rethink or remove Form Groups - the currently implementation falls short of expectations
• Consider adding semantic icon sizes utilities to Skeleton (ex: icon-sm, icon-md, etc)
• Resolve textarea sizing in appropriately for large container radius sizes

Documentation Updates

• Move [Lists](https://www.skeleton.dev/docs/svelte/design/typography#lists) from Typography docs to their own top-level section for better discoverability.
• Consider splitting the overstuffed Forms/Input documentation (especially range/progress)

Requirements

This ticket should be treated as an the parent for this initiative. All findings should be attached as sub-item tasks.

Task: Review Tailwind Layers

It's been brought to our attention that a number of components are hard to override with utility classes (ex: table). Let's review what layers are used and what techniques can be utilized to improve this experience.
