Removes duplicated locale logic from +layout.svelte and AppNav.svelte.
Context-specific sizing (text-xs/min-h-[44px]) stays in the wrapper
via [&_button]: selectors so the component itself is layout-agnostic.

- AppNav: hide entire logo div (incl. mr-10 margin) below md: breakpoint
to eliminate the phantom whitespace left of the hamburger button
- admin: 2×2 grid on mobile → flex row at sm:, so "Schlagworte" fits

On mobile the header is now cleaner — language buttons move to the
bottom of the hamburger panel. Desktop header is unchanged (sm:flex).

On mobile the text consumed most of the header width, leaving no room
for the hamburger, theme toggle, and user menu. Uses hidden sm:inline —
aria-label on the anchor preserves screen reader access at all sizes.

Nav links were completely hidden on mobile (sm:flex / hidden split).
Adds a 44×44px hamburger toggle, a fixed overlay panel with full-width
nav links (min-h-[44px] touch targets), backdrop-click and Escape to
close, and a $effect that auto-closes on route change.
