fix(ci): unblock CI lint by allowing any in OIDC/OAuth test files

The OIDC and OAuth test files (added in #1056) inspect the dynamic
NextAuth provider object and use `any` for ergonomic property access.
That trips @typescript-eslint/no-explicit-any (error level), which has
been failing CI on main since 2026-05-02.

Add a file-level eslint-disable for that rule in both test files.
This is the standard pattern for tests that poke runtime-shaped
objects, and keeps the rule strict everywhere else.

Local: npm run lint -> 0 errors, npm test -> 709/709 passing.
