fix: model list cut off at bottom in ModelSheet

Fixes #245

Hi Experts,

I’d like to provide some context that may help save you time when reviewing my code. When fixing this issue, I considered several options:

Option 1: Use a fixed value of 100
In my testing, this value worked well. It wasn't too large or too small, and the display effect was great.

Option 2: Use HEADER_HEIGHT + TAB_BAR_HEIGHT
This is simply because both of these are heights of top components. However, logically, there is no causal relationship between using them to calculate the bottom padding. It would avoid defining a new variable and the values are quite close to each other.

Option 3: Dynamically calculate (measure the list item height)
This solution seems to be the best. However, the current module list's height is determined by the content, and there is no fixed height constant. If we use onLayout for dynamic measurement, the padding would initially be 0 during the first render, which could lead to flickering. This seems like quite a bit of work and would introduce some uncertainty, so I don't think this approach is worth it. Perhaps in the future, more experienced developers may consider it.

Given all these considerations, I opted for Option 1, which I think strikes the right balance.

Let me know if you have any thoughts or suggestions!

BR,
Marshu

In fact, fixed values should not be used for processing. I adjusted the model sheet, and currently this effect can solve the problem while keeping consistency on both iOS and Android sides.
