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.

+## Same-Origin, Single-Process Mode
+
+For an edge/dev setup where running a separate `npm run dev` process is too heavy,
+the backend can serve the built console directly from the same process:
+
+```bash
+VITE_API_BASE_URL= npm run build
+RUNTIME_CONSOLE_STATIC_DIR=$(pwd)/dist uvicorn api.rest:create_app --factory --host 127.0.0.1 --port 8000

+`VITE_API_BASE_URL=` (empty) makes the build use relative API paths so it works
+same-origin without CORS. The console is then served at `/ui/` (with `/`
+redirecting there); `/console/*` remains the JSON API used by both this mode
+and local `npm run dev`. Rebuild (`npm run build`) after frontend changes —
+this mode does not hot-reload.
