feat: 🚀 upgrade SDK, deps, and fix any deprecations in the way + FVM

[YazeedAlKhalaf]

Flutter version upgraded to is the latest stable as of today: 3.22.1.

This PR upgrades everything to the latest version possible, and it also includes fvm so that it is easier to have the same environment for contributors.

Things I did in points, hopefully nothing is missing:

• Added docs about FVM usage, and labeled it optional.
• Upgraded all dependencies to latest possible.
• Minimum deployment version for iOS is 12.0 now, since path_provider, shared_preferences, and url_launcher don't support iOS 11.0 anymore
• I used this list to map the new text theme along with flutter fix: https://docs.flutter.dev/release/breaking-changes/3-19-deprecations
• selectedRowColor was deprecated in 3.16 and here is what I followed: https://docs.flutter.dev/release/breaking-changes/3-16-deprecations#themedata-selectedrowcolor
  • The framework doesn't use it anymore, it uses other things. I migrated the two usages by hard coding them for now. We can perhaps create a theme extension to hold custom values like this if needed.
• Impeller is enabled now for iOS by default and its performance is good, but for Android is it disabled cuz still not the best experience IMHO.
• I had to follow the flutter_local_notifications android guide again for some changes: https://pub.dev/packages/flutter_local_notifications#-android-setup
• I also disabled material 3, which looked weird and broke lots of things. material 2 looks better on Noor.
• remove a launch.json in android folder related to dart :D
• I also migrated to the new "declarative way" of gradle, seems everything is declarative now 😂. I recreated the android project and made sure things work as expected.

Lots of changes, so feel free to reject or test and merge, hopefully the later 👀.

this is the only remaining deprecation:

'window' is deprecated and shouldn't be used. Look up the current FlutterView from the context via View.of(context) or consult the PlatformDispatcher directly instead. Deprecated to prepare for the upcoming multi-window support. This feature was deprecated after v3.7.0-32.0.pre.
Try replacing the use of the deprecated member with the replacement.
