[i18n] RTL Support for Arabic & Persian Languages

[fbenmadani]

Add full Right-to-Left (RTL) support for local languages such as Arabic and Persian.

Scope:

• Detect RTL locales (ar, fa)
• Apply dir="rtl" dynamically in layout
• Ensure Tailwind/CSS supports RTL (via logical properties or RTL plugin)
• Mirror UI components (navbars, forms, tables, modals)
• Validate third-party components compatibility
• Adjust icons (directional icons flipping)

Technical Tasks:

• Add locale-based direction helper
• Integrate RTL-compatible styling strategy (e.g. tailwind-rtl or CSS logical props)
• Test all core صفحات (dashboard, auth, CRUD)

Outcome:
Users can seamlessly use the platform in RTL languages with correct layout and UX.

Notes:

• Avoid hardcoded margin-left/right; use start/end
• Consider future multilingual expansion
