Improve catalog table responsiveness

[saahithjanapati]

Summary

• wrap each catalog table in a responsive container so wide tables remain accessible on small screens
• update catalog styles to use auto table layout, ensure horizontal scrolling, and stack action buttons on narrow viewports

Testing

• CI=true npm test -- --watchAll=false (fails: existing App.test.js sets react-modal app element without a #root in the test DOM)
