chore(sync): mirror backend .py + Dockerfile to Space (hf-sync-backend)

Automated backend sync from szl-holdings/a11oy main via hf-sync-backend.
Updated (differed from the Space): Dockerfile, szl_connector_mcp.py, szl_connectors/__init__.py, szl_connectors/base.py, szl_connectors/bindings.py, szl_connectors/comms/__init__.py, szl_connectors/comms/comms_connectors.py, szl_connectors/crm/__init__.py, szl_connectors/crm/crm_connectors.py, szl_connectors/data_sources/__init__.py, szl_connectors/data_sources/geo.py, szl_connectors/data_sources/macro.py, szl_connectors/data_sources/maritime_air.py, szl_connectors/data_sources/research.py, szl_connectors/data_sources/security.py, szl_connectors/erp/__init__.py, szl_connectors/erp/erpnext.py, szl_connectors/erp/odoo.py, szl_connectors/erp/others.py, szl_connectors/erp/sap_s4.py, szl_connectors/governance.py, szl_connectors/identity/__init__.py, szl_connectors/identity/identity_connectors.py, szl_connectors/itsm/__init__.py, szl_connectors/itsm/itsm_connectors.py, szl_connectors/oauth.py, szl_connectors/observability/__init__.py, szl_connectors/observability/observability_connectors.py, szl_connectors/ready.py, szl_connectors/registry.py, szl_connectors/storage/__init__.py, szl_connectors/storage/storage_connectors.py, szl_connectors/warehouse/__init__.py, szl_connectors/warehouse/warehouse_connectors.py, szl_connectors_serve.py

Keeps the Space-built backend (serve.py + the Dockerfile-COPY'd .py
modules) identical to GitHub main so the Space never rebuilds from a
stale backend and new endpoints don't 404 there.

+"""szl_connectors.base — the ONE connector abstraction (not N hacks).
+
+Every enterprise CRM/ERP/platform/data-source binds to a single `Connector`
+base class. Each provider is a thin subclass whose ONLY per-provider variation
+is the body of `health()` / `read()` / `write()` (the real HTTP) + the auth
+wiring. The UI, the MCP layer, and the governance layer treat every connector
+identically.
+
+HARD DOCTRINE (non-negotiable — woven throughout):
+  • NO fabricated records. A connector returns REAL live provider data
+    (CONNECTED), an honest empty READY ("provide credentials to activate" +
+    the exact secret name), or a clearly-LABELED SAMPLE (`sample_reason` set,
+    used ONLY where no free tier exists). ERROR is honest.
+  • NO committed keys. Every credential is read from env/Space-secret ONLY.
+    Receipts store credential FINGERPRINT HASHES, never the key value.
+  • Every write() is Λ-gated (Λ never 1.0) + DSSE/Khipu-receipted.
+  • Trust never 100% (conformal anti-overconfidence floor 1/(n+1)).
+  • 0 runtime CDN in served apps; these are live DATA fetches (data, not code).
+
+This generalizes the proven honest-state discipline already shipping in
+`szl_a11oy_live_feeds.py` (CISA KEV / NVD / arXiv wired live, labelled
+`live: true/false` + `source_status`) into a first-class connector framework.
+
+API references targeted (publicly documented shapes; SZL writes its own
+original client code, never copies proprietary SDK code) — see each subclass
+module's docstring + the package NOTICE.

+"""szl_connectors.oauth — the OAuth2 authorization-code + PKCE flow engine (P2).
+
+Designed NOW; activates the instant a customer provides an OAuth app
+registration (CLIENT_ID/CLIENT_SECRET). The redirect URI is a stable per-app
+path: https://<space>/api/{app}/v1/connectors/{id}/oauth/callback
+
+Flow (per ENTERPRISE_INTEGRATION_SPEC §1.3):
+  1. /oauth/start  → 302 to provider authorize URL with client_id, redirect_uri,
+                     scope, state (= signed nonce), code_challenge (PKCE S256).
+  2. provider → user consents → redirects to /oauth/callback?code=&state=
+  3. /oauth/callback → verify signed state nonce → POST code to provider /token
+                     (client_id + client_secret + code_verifier) → access_token
+                     + refresh_token.
+  4. Persist ONLY to the secret store (env injector / Space secret) — NEVER to a
+     file or commit. Emit a DSSE "credential-bound" receipt carrying ONLY the
+     connector id, granted scope, and a credential FINGERPRINT HASH (never the
+     secret value).
+  5. health() now sees the refresh token → exchanges for access token → CONNECTED.
+
+DOCTRINE: no committed keys; the secret value never leaves the secret store and
+never enters a receipt body. Until CLIENT_ID/SECRET are provided, the connector
