feat: surface per-user credentials to feed source providers

Add credentials parameter to FeedSourceProvider.feedSourceForUser so
providers can receive decrypted per-user credentials (OAuth tokens,
passwords) from the user_sources table.

Wire CredentialEncryptor into UserSessionManager to handle
encrypt/decrypt. Providers receive plaintext and handle validation
internally. Existing providers ignore the new parameter.
