Return EvCompany logo as a full URL in the API resource

EvCompanyResource returned the raw disk-relative path stored by
Filament's FileUpload (e.g. "logos/xxx.png"), not something API
consumers can render directly.

- EvCompany::logoUrl() builds an absolute URL from the configured
  filesystem disk, guarding against a disk (e.g. s3) that already
  returns an absolute URL so it isn't double-prefixed.
- EvCompanyResource now exposes that as 'logo' instead of the raw path.
