fix: switch feeds table from flex divs to proper <table> element

The flexbox div approach had rendering issues (header misaligned, columns
not lining up). Replaced with a real <table class='feeds-table'> with
<thead>/<tbody>, native <th>/<td> cells, and border-collapse for clean
row borders. Column widths are now enforced by the table layout engine:
38px checkbox cols (centered), flexible URL col, right-aligned hint col.
