This commit adds the new Notes column to the report page which will show
all the available notes entered for a specific test case.

The commit also changes the layout of the table, it makes the main
report table responsive so it can scroll horizontally, this way columns
can have a specific size and look better in the page.

The test case ID and notes column now have a specific width size, giving
more space to their cells.
