[Feature request] RTL mode

Title: RTL not supported in EnrichedTextInput

Describe the bug:
EnrichedTextInput does not support RTL mode. Even when the app is in RTL layout:
The placeholder always stays left-aligned.
Ordered list numbers, bullets, and blockquote markers always start from the left.
Only the typed text appears to start from the right (but formatting is inconsistent).

To Reproduce:
Use a simple EnrichedTextInput in an RTL layout.
Observe the placeholder alignment (always left).
Apply formatting such as Ordered List or Blockquote.
See that list numbers, bullets, and blockquotes remain left-aligned.

Expected behavior:
All elements (placeholder, list numbers, bullets, blockquotes) should respect RTL.

Actual behavior:
Placeholder: always left-aligned ❌
Lists and blockquotes: always left-aligned ❌
Input text: appears on the right ✅

Device:
Device: any
OS: any
Version: any

Additional context:
RTL is not supported in EnrichedTextInput at this time.

Start by reproducing the issue with a simple EnrichedTextInput in an RTL layout, then inspect how placeholder alignment, ordered lists, bullets, and blockquotes are rendered. The work is done when all of these elements respect RTL while typed text and formatting remain consistent.
