fix: blank inbox previews, two unauthenticated 500s, and the missing social tests
- Every conversation row in the inbox rendered an empty preview: the frontend read `last_body`, which the API has never sent. It sends `excerpt` plus `truncated`. - `GET /api/codex?limit=-1` passed a negative LIMIT to Postgres -> 500. Now bounded by Query(ge=1, le=200) -> 422. - Registering with a >255 char email hit the VARCHAR(255) column and surfaced as a 500. PATCH /api/profile already validated this; only /auth/register was open. The social layer had zero tests, despite routes/messages.py citing "tests/test_messages.py's cross-user leak tests" and routes/profile.py claiming "privacy rules that the tests pin". Neither file existed. Both now do: auth required on every route, email only on /api/profile/me, no id or password_hash on any public payload, third-party thread reads empty, payload-supplied sender inert, veiled profiles 404 and stay off the roster.
