It's slang for a bad knockoff, a tawdry copy of something. Temu is a Chinese retail site selling knockoffs of other companies' products, but they have the knockoffs made in sweatshops by slaves in Xinjiang for nothing. That way, the site can sell stuff cheaper than anyone else. China also has a very "flexible" view of the intellectual property rights, patents and trademarks of other nations, which saves them money when they rip off products.
She got above scale, though, because she had lines beyond a certain minimum in many eps, even if they weren't very interesting lines. That meant a bit of steady income for when a show made it into syndication, if I recall correctly. One of the Next Gen podcasts had a recurring bit in which they would celebrate with silly sound effects when a day player, like that sickbay nurse, reached the minimum number of lines to get that pay bump. EDIT: NURSE OGAWA!
