fix(sqllab): fix blank bottom section in SQL Lab left panel

[gabotorresruiz]

SUMMARY

Fixed an issue where the bottom half of the SQL Lab left panel was appearing blank. The problem was caused by improper height calculations using fixed pixel values instead of flexbox layout. The component was using a hardcoded height prop (defaulting to 500px) and calculating the table area as height - 130px, which left empty space at the bottom

TESTING INSTRUCTIONS

1. Open SQL Lab
2. Select a database and schema in the left panel
3. Add some tables to view their columns
4. Verify that the left panel properly fills the entire height without blank space at the bottom
5. Test resizing the browser window to ensure the layout remains responsive
6. Switch between different databases/schemas to ensure the layout remains consistent
