Swaps navbar layout (theme toggle left, nav links right), replaces the
mobile dropdown with a fullscreen overlay whose items fly in top-to-bottom,
and renames the site-wide "slate" gray to "neutral" to remove a blue
undertone that clashed with the brand green. Also converts the flat
saturated-green YouTube and stats sections into dark backgrounds with
green used only as an accent, matching typical premium car-audio branding.

Adds a Website settings tab (hero image, phone, WhatsApp, email) that
feeds the navbar, footer and contact page via a new SiteSettingsContext,
redesigns the navbar with a bigger centered logo plus phone/WhatsApp/shop
links, and adds a VIN/chassis-number field to the contact form, admin
inbox and notification email.
