fix(next): remove error handling from next auth functions (#12897)

The `@payloadcms/next/auth` functions are unnecessarily wrapped with
`try...catch` blocks that propagate the original error as a plain
string. This makes it impossible for the end user's error handling to
differentiate between error types.

These functions also throw errors regardless, and therefore must be
wrapped with proper error handling anyway. Especially after removing the
internal logging in #12881, these blocks do not serve any purpose.

This PR also removes unused imports.
