Unify table on the home page

[EshaanAgg]

I have added the basic functionality related to merging the UI of the two tables in the Overview component. I would highly appreciate it if @PhilippWendler, sir you could check if the table is performing as expected in terms of allowing the users to:

• Select columns
• Filter data
• Resize columns
• Sticky headers

After the same is completed, I would work on improving the UI as per the suggestions, and then would update the test suite as well as the build.

Fixes: #506
