refactor: A28 lot 1 — api_v2.py (2 110 L) → package 14 fichiers (v7.29.0)

Découpe par concern de l'ancien app/routers/api_v2.py (2 110 lignes,
115 routes) en package `app/routers/api_v2/` :

- 12 modules de routes : collections 566 L (23 r.), engagement 338 (21),
  workspaces 230 (9), templates_io 205 (9), webhooks 195 (8),
  identity 195 (7), views 164 (8), sharing 160 (8), properties 151 (7),
  planning 148 (7), projects 93 (4), admin 91 (4)
- `_common.py` : helpers partagés (_hash, _v2_rate_check)
- `__init__.py` : router = APIRouter(prefix="/api/v2") + include_router
  sur les routers de sections (sans prefix, tags « api-v2 »)

Preuve contractuelle : `docs/openapi-v2.json` régénéré = IDENTIQUE
byte-à-byte (0 changement de chemin/tag/operation_id). Seul importateur
(app/main.py : from app.routers.api_v2 import router) fonctionne via le
package. En-tête d'imports copié par module puis émondé par ruff --fix
(143 imports morts), I001 réordonnés.

Reste A28 : dashboard.py 2 735 L, collections.py 2 622 L, board.py 2 101 L
(même recette, lots suivants).

 # Changelog - FlowDeck
 
+## v7.29.0 (2026-10-01) — Audit : A28 lot 1 (api_v2 → package 14 fichiers)
+
+### Changed
+
+- **A28 lot 1** : `app/routers/api_v2.py` (**2 110 lignes, 115 routes**)
+  devient le package `app/routers/api_v2/` — un module par concern :
+  · `collections` 566 L (23 routes), `engagement` 338 (21), `workspaces`
+    230 (9), `templates_io` 205 (9), `webhooks` 195 (8), `identity` 195 (7),
+    `views` 164 (8), `sharing` 160 (8), `properties` 151 (7),
+    `planning` 148 (7), `projects` 93 (4), `admin` 91 (4)
+  · `_common.py` : helpers partagés (`_hash`, `_v2_rate_check`)
+  · `__init__.py` : `router = APIRouter(prefix="/api/v2")` + agrégat
+    `include_router` (section routers sans prefix, tags `api-v2`)
+- Preuve contractuelle : **`docs/openapi-v2.json` régénéré = identique
+  byte-à-byte** (0 changement de chemin, tag ni operation_id)
+- Seul importateur (`app/main.py` → `from app.routers.api_v2 import
+  router`) fonctionne via le package ; en-tête d'imports copié par module,
+  émondé par `ruff --fix` (143 imports morts supprimés automatiquement)
+
+### Notes
+
+- Reste A28 : `dashboard.py` 2 735 L, `collections.py` 2 622 L,
+  `board.py` 2 101 L (même recette, lots suivants)
+- Suite complète : **1091/1091** · ruff OK
+
+## v7.28.0 (2026-10-01) — Audit : A42 TERMINÉ (client httpx partagé)
+
+### Changed
+
+- **`app/services/http_client.py`** : `async with shared_client(timeout=15)
+  as client:` remplace les **49 créations `async with httpx.AsyncClient(`**
+  réparties dans 14 fichiers (gitea ×21, providers ×11, calendar ×4,
+  automations ×3, …) — le pool de connexions est réutilisé au lieu d'être
+  recréé à chaque appel
+- Cache **par (boucle d'event, kwargs)** en `WeakKeyDictionary` : un
+  `AsyncClient` n'est jamais partagé entre deux loops (le piège des tests :
+  « Event loop is closed ») — une boucle par test = un client propre,
+  collecté avec elle. Clé = kwargs triés, `repr()` pour les valeurs non
+  hashables (`headers=` dict)
+- Context manager no-op à la sortie (pas de fermeture du client partagé) ;
+  `ponytail:` documenté : pas d'`aclose` explicite, plafond = pools non
+  fermés à la main (GC des sockets), upgrade = lifespan
+- **Laissés délibérément** : `github_adapter` (transport MockTransport
+  injecté), `webhook_outbound` (client « own_client » fermé par la fonction)
+
+### Tests
+
+- `test_http_client_shared_and_loop_scoped` : réutilisation (mêmes kwargs),
+  cloisonnement par kwargs, cloisonnement par boucle (2× `asyncio.run`)
+- Stub webhooks : patch étendu à la fabrique `http_client.httpx` + purge du
+  cache (les tests patchaient `webhook_outbound.httpx`, contourné par la
+  fabrique partagée)
+- Suite complète : **1091/1091**
