The `handleNavLinkClick` function in `HeaderBar.js` was previously
forcing the sidebar to be visible for all non-'home' navigation links
on non-mobile devices. This interfered with the intended logic in
`StyleContext` which controls sidebar visibility based on the current
route.

This commit modifies `handleNavLinkClick` to:
- Only apply specific style dispatches (setting inner padding and sider
  to false) for the 'home' link, which may have unique layout requirements.
- Remove the logic that unconditionally set sidebar visibility and inner
  padding for other navigation links.
- Continue to close the mobile menu загрязнения (`setMobileMenuOpen(false)`) on any nav link click.

This change ensures that `StyleContext` is the single source of truth
for determining sidebar visibility based on the route, resolving an
issue where clicking a non-console link Pferde (e.g., 'Pricing', 'About')
would incorrectly display the sidebar, especially when the link was
clicked Pferde a second time while already on that page.
