## What
On the very first load (full browser refresh), the navigation skeleton
didn't match the real `NavigationDrawer` width: it rendered an 8px-wider
panel (an 8px wrapper padding on top of the 220px animated container)
and right-aligned 204/196px item rows, so the menu visibly shifted and
resized once the app finished loading.
This makes every navigation skeleton mirror the real drawer geometry: a
single `NAVIGATION_DRAWER_CONSTRAINTS.default`-wide (220px), border-box
panel with the drawer's own padding, left-aligned, and skeleton bars
that fill the content width like the real nav items (`width: 100%`). The
same fill-width fix is applied to the in-drawer section skeletons so
every navigation skeleton matches the real menu width.
## Verification
- `tsgo` typecheck, `oxlint`, and `oxfmt` all clean on the changed
files.
