style: table-like layout for feeds management view

Restructured feed-toggle-list into a proper table layout:
- Two fixed-width checkbox columns on the left (Enable, Re-enrich)
- Feed URL column takes remaining space
- Last-seen column right-aligned
- Header row with uppercase labels
- Border-radius container with row separators
- Moved all inline styles to CSS (.feed-col-check, .feed-col-url, .feed-col-hint)
