syz-manager: modernize web UI

1. Use dashboard style.
2. Allow sorting of tables.
3. Show old crashes in grey.
4. Use tables instead of text output for more pages.
5. Show corpus inputs on a separate page to allow copy-pasting.
6. Use standard JS sorting instead of custom bubble sort (much faster).
7. Fix off-by one in table sorting.

Fixes #694
