Fix: Resolve search filter controls overlap on findings page (#901)

[sahare-mayur-0071]

Fixes #901

• Updated the filter container in \Findings.tsx\ to use flex column instead of forcing components inline via rigid grid templates on large screens.
• Limited filter grid to a max of 4 columns, preventing inputs from becoming too narrow and clipping text.
• Assigned \min-w-0\ to field containers to ensure they respect the grid cells.
• Stacked the actions controls below the filter grid to guarantee they don't crash into each other.
