fix: A21 phase 2c — 190 routes hors loop, 86 % total (v7.26.0)

4 passes (283 → 93 routes async sur 667 = 86 % hors loop, avant 61 %) :

A. RACINE AUTH — `get_current_user` (auth/session.py) était `async def`
   SANS aucun await (cookie decode = synchrone) ; idem ses clones :
   `agent._current_user_id/_workspace_id/_current_admin` (34 sites) et
   `sso._require_admin` (corps 0 await, 6 sites) → `def` +
   47 `await` supprimés. Piège : 3 call sites passaient par l'alias `gcu`
   (grep littéral aveugle) — 8 tests en échec → corrigés.

B. Re-scan : 19 routes devenues SANS await → `def` (agent 8, sso 5,
   web_clipper 3, projects 2, auth 1…).

C/D. 155 routes dont les seuls awaits = `request.json()` / événements :
   - try/except `body = {}` → `Body(default={})` (même tolérance)
   - try/except `raise HTTPException(400)` → `Body(...)` REQUIS
     (422 FastAPI — aucun test ne couvrait le 400)
   - forme conditionnelle `request.json() if content-type else {}`
     (54 sites) → défaut `{}` (sans corps = `{}` dans les 2 cas)
   - `await fire_*` → `run_event_sync(...)` ; imports `Body` /
     `run_event_sync` ajoutés aux routers convertis

Reste async (93, justifié) : form/upload/file (22), réseau gitea/llm/oidc,
`_json_body` (9), 2 JSON inline en argument, 1 fallback logique
(capture_frontend_error), 1 lecture conditionnelle (web_clipper), mixtes.
