Feat: Use ModalBottomSheetLayout in bottom sheet in send screen

[Prakhar-Agarwal-byte]

Fixes #284

[thunderbiscuit]

Tell me more about your changes when you open PRs if you can. For example, I see that ModalBottomSheet was introduced in Material 3 Compose 1.2.0-alpha01, but I also know that your PR #323 uses the BOM to fix the dependencies, including Material 3 to 1.1.1. Do those interact? In theory the ModalBottomSheet should not be available, unless we also fix the gradle dependency but I don't see that here, so I'm a bit unsure. Was it maybe marked as experimental and now is not? Also is that related to the bug I find on the SendScreen in #323? (should I consider one PR dependent on the other for example?).

Here is what the send screen looks

like on my machine (i.e. it's missing the background)

[Prakhar-Agarwal-byte]

Both PRs #323 and #324 are separate and not interrelated. The background is also missing in my machine, it is yet to be fixed. I will need to give it more time.

[Prakhar-Agarwal-byte]

If we can merge #323, I will be able to include the changes in this PR on top of that.

This PR will also need a quick rebase.

This PR still has an issue with the top app bar background color. It is white but should be green as with the other screens.
