tanin-eww: niri focus-ring tracks the TANINUX accent

The focus-ring active-color was a static Fuji violet (#a39ec4); it now
follows gui.json's accent_hex, lightened 8% to match eww's $accent. The
scripts/accent.sh apply step patches the marked active-color line in
~/.config/niri/config.kdl (niri live-reloads on save); the line carries a
managed-by marker, anchored at line start so it never matches inactive-color.
