refactor: apply usePortalModeClasses to remaining portaled components

[Harsh-Anand-Singh]

Description

This draft PR applies usePortalModeClasses to the remaining portaled components so portal-mode styling follows the same shared pattern across the codebase.

Some components already preserve portal-mode classes correctly when rendering through portals, while others still rely on component-specific handling. This change aligns those implementations and closes the remaining propagation gaps.

Changes

• apply usePortalModeClasses to remaining portaled components
• replace inconsistent component-level portal-mode handling with the shared hook
• add or update tests covering portal-mode class propagation

Why

This keeps portal behavior consistent across components and reduces the chance of styling mismatches when content is rendered outside the normal DOM tree.

Testing

• updated relevant tests for affected portaled components
• verified portal-mode classes propagate as expected in portal-rendered content
