create_task.py: migrate REST /api/v2.0 -> midclt (removed in TrueNAS 26.04)

The tool created cloud_backup tasks via POST /api/v2.0/cloud_backup, which is deprecated
and removed in TrueNAS 26.04. It now calls the middleware directly with midclt
(cloudsync.credentials.query / cloud_backup.query / cloud_backup.create), so it runs on
the TrueNAS host with no host address or API key. --host/--api-key/--insecure are kept
accepted-but-ignored for compatibility. Dropped the ssl/urllib HTTP client. v0.2.0.

 # Changelog
 
+## v0.2.0 — 2026-07-08
+
+### Changed
+
+- **`create_task.py` now uses the TrueNAS middleware via `midclt` instead of the
+  deprecated `/api/v2.0` REST API**, which is removed in TrueNAS 26.04. Practical
+  effects:
+  - Run the script **on the TrueNAS host** — it uses the local middleware socket, so
+    it no longer needs a host address or API key.
+  - `--host`, `--api-key`, and `--insecure` are accepted but **ignored** (a deprecation
+    note is printed); they will be removed in a future release.
+  - `list-credentials` → `cloudsync.credentials.query`, `list-tasks` →
+    `cloud_backup.query`, `create` → `cloud_backup.create`.
+- Dropped the `ssl`/`urllib` HTTP client; no TLS certificate handling is needed anymore.
