pikpak: improve getFile() usage

Previously, `getFile()` was called indiscriminately during uploads, moves, 
and download link generation. This could lead to users with download limit 
causing subsequent operations like uploads and moves to fail. 
This PR optimizes the use of getFile(), by only calling it 
when it's strictly necessary.
