Fix EV company logo upload to use public disk

Logos were being written to the default filesystem disk, which
resolves to storage/app/private and isn't web-servable, so the
frontend couldn't load the image. Store logos on the public disk
(storage/app/public, symlinked to public/storage) instead, and
resolve logoUrl() against that disk explicitly.
