Added a backup API endpoint

[MightyZanark]

As of truthversion 10053000, Priconne has obfuscated their database table and column names (https://x.com/_Todo_Kirin/status/1746794572133392689?s=20), which just breaks all the SQL queries.

Currently, estertion's database API is still in the hashed version, but wthee's seems to have a work around for it (which is still temporary as it is comparing the readable version of the database with the hashed one), so I have added their API endpoints as a backup for the time being. The database that's broken is the jp database, but since I thought that it would add a conditional on UpdateManager if I only changed the jp endpoints, I also changed the cn database endpoint.
