fix(sponsorList): correct property name for special sponsors display

The display page was referencing an incorrect property `specialSponsor` instead of `specialSponsors`, causing the list not to render. This has been corrected.

Additionally, the sponsor data file has been updated with new entries and corrections, including moving '地南祥子' from a table sponsor to a cash donation.
