[Table] Normalize type signatures and fix sub-pixel border

[ravisuhag]

Summary

Table is a custom semantic HTML table wrapper using CVA + CSS Modules. Missing displayName on all sub-components, accessibility attributes, and API completeness.

Improvements

6. Normalize type signatures across sub-components

TableHead and TableCell use CVA variants but TableBody and TableRow don't. Inconsistent API surface.

7. Handle text truncation accessibility

Cells use text-overflow: ellipsis which hides content with no tooltip or accessible overflow mechanism.

Moved to Cross-Cutting Issues

The following items have been moved to cross-cutting issues that address them across all components:

• Replace hardcoded CSS values with design tokens (Replace hardcoded CSS values with design tokens #672)
• Accessibility baseline (Accessibility baseline: aria attributes, roles, and semantic HTML #673)
• Add displayName (Add displayName to components and sub-components #676)
