add rtl support

[3adeling]

In this PR, I implemented RTL support without impacting LTR functionality, taking all screen breakpoints into account.

Here’s a summary of the changes:

• Replaced pl-* and pr-* classes with ps-* and pe-*
• Replaced ml-* and mr-* classes with ms-* and me-*
• Substituted left-* and right-* with start-* and end-*
• Added rtl:space-x-reverse for all TailwindCSS screens where space-x-* was used
• Adapted all transitions for LTR and included reversed transitions for RTL
• Added APP_LOCALE, APP_FALLBACK_LOCALE, and APP_FAKER_LOCALE to .env.example and referenced them in config/app.php
• Set dir="ltr" in all layout files

These changes will only take effect if dir="rtl" is specified, either by hard-coding or dynamically setting it based on the app’s locale, for example: dir="{{ app()->getLocale() == 'ar' ? 'rtl' : 'ltr' }}".

Wow! Thanks for the amazing PR. Considering this is a lot of UI updates I want to test many of this manually and make sure everything still looks good. Appreciate the PR. I'll be testing this out soon.
