[FR] Android App - Table clips off not utilizing the entire screen making it hard to see

### Bug Description

Open a database table view and only part of the table is visible while there is a blank area below it. Scrolling within the visible part is possible

### How to Reproduce

Open a table view with about 15 rows of data

### Expected Behavior

I would expect that the table would take up all available space on the screen then scroll if needed. Also I expect that calculations should be possible as per the website and other internet searches say it is. I do not see a way to calculate below the Add New bar at the bottom of the table.

### Operating System

Android 15

### AppFlowy Version(s)

0.13.0

### Screenshots

### Additional Context

_No response_

Start by reproducing the table view on Android 15 with AppFlowy 0.13.0 and inspect the mobile table layout, scrolling area, and bottom Add New bar. Done means the table uses the available screen height, scrolls through all rows, and the expected calculation controls are accessible or their absence is clarified.
