style(cloud): reformat modules and restore except-tuple parentheses

Apply consistent line-length formatting across governance, plugins, the
SDK routers (governance_api, user_api), user_auth, and migrations
0003/0005/0006.

Also restore the parentheses on two except clauses that had been dropped
into invalid Python 3 `except A, B:` syntax: plugins._coerce_to_manifest
(KeyError, ValueError) and PasswordHasher.verify (InvalidHashError,
VerificationError). Both modules now import cleanly again.
