fix(sidebar): centre Playlists icon and unify hover hitbox in collapsed mode (#481)

* fix(sidebar): centre Playlists icon and unify hover hitbox in collapsed mode

The Playlists nav entry had its own special render path with a wrapper
div, header-row and `flex: 1` main link to fit the expand-toggle
button. Those elements remained active in collapsed mode too, where
`padding-right` on the header-row and `flex: 1` on the link made the
icon sit off-centre and gave the row a wider hover hitbox than every
other collapsed sidebar item.

Hoist the `isCollapsed` check above the playlists special-case so that
in collapsed mode Playlists renders through the same plain `<NavLink>`
branch as Artists / Albums / Favorites / etc. The expanded-mode
treatment (wrapper, header-row, expand-toggle, nested playlist list)
is unchanged.

+### Sidebar — Playlists icon and hover hitbox in collapsed mode
+
+**By [@Psychotoxical](https://github.com/Psychotoxical), PR [#481](https://github.com/Psychotoxical/psysonic/pull/481)**
+
+* The **Playlists** icon in the collapsed sidebar was **off-centre** and had a **wider hover background** than every other item, because it still rendered through the expanded-mode wrapper (with `padding-right` and a `flex: 1` main link to fit the expand-toggle). Collapsed mode now reuses the **standard nav-link path** — same hitbox, same alignment as Artists, Albums, Favorites, etc.
