+Fix token-type-mismatch error when using multiple `acceptsToken` values in `authenticateRequest`. When `acceptsToken` is an array containing both session and machine token types (e.g., `['session_token', 'api_key']`), the function now correctly routes to the appropriate authentication handler based on the actual token type, instead of always treating them as machine tokens.

+Fix redirect conflicts when SignIn and SignUp components are used together on the same page. Added missing dependency arrays to useEffect hooks in redirect functions to prevent unwanted redirects during other component flows.
