1-3095: small UI tweaks sidebar boxes (#8721)

This PR fixes three minor UI issues:
1. The modal is too wide. Turns out that `SidebarModal` has a fixed
width of 1300. `DynamicSidebarModal` does not, so that switch makes it
much leaner.
2. The lifecycle boxes should grow in width to fill whatever space they
have available.
3. If you have 1 flag in any of the stages, we should say "1 flag"
instead of "1 flags".

Sidebar before:

Sidebar after:

The lifecycle boxes at their very widest:
