[Concern] The shimmer loading view doesn't match with design

[minhnimble]

Why

The application needs to show the initial shimmer loading view with animation after first entering the app with a valid logged in session like design. Currently, the loading only shows the animated top components (title, circle avatar) with incorrectly horizontal length compared to the design:

Acceptance Criteria

• The skeleton loading view needs to look like the following design with sufficient animated components:

The first approach that I could think of when implementing this shimmer loading is to create a dedicated composable view just to contain all the shimmer composable, but then I think that way would make code duplicated while we can use just one composable to show shimmer and display the data with a customized shimmer Modifier, then in future, if we need to implement shimmer loading in other screens, we don't need to create another composable as well. But this way clearly has 1 disadvantage as you pointed out above. I will be fixing this by applying the first approach.

I improved the shimmer loading in this PR, which I also attached a demo video for the inspection
