Fix TypeError creating B2 tasks on TrueNAS 24.10: handle both credential schemas

On 24.10 (Electric Eel) credentials["provider"] is the type string with
account/key in credentials["attributes"]; 25.04+ moved them into a
provider dict. The injected get_restic_config only handled the newer
shape and raised TypeError on 24.10 at task creation (#1).

The method now detects the schema and reads credentials from the right
place on both. create_task.py list-credentials and list-tasks use the
same schema-agnostic lookup.

 # Changelog
 
+## v0.0.4 — 2026-07-06
+
+### Fixed
+
+- **Backend patch inactive after every reboot.** PREINIT initshutdownscripts
+  are executed by middlewared itself (`ix-preinit.service` runs
+  `midclt call initshutdownscript.execute_init_tasks PREINIT`, ordered after
+  `ix-zfs.service` pool import). By the time `apply.sh` patched `b2.py` and
+  `restic.py` in the overlay, the running middlewared had already imported the
+  stock modules and never re-imports — so S3/B2 support silently reverted on
+  every reboot until something restarted middlewared. `install.sh` masked the
+  bug because it restarts middlewared explicitly.
+
+  Fix: when `apply.sh` detects it was invoked by middlewared (boot context),
+  it now schedules a single detached restart via a transient systemd unit
+  (`truecloud-mw-restart`, ordered after `multi-user.target` and
+  `ix-postinit.service`) so the patched modules are loaded once boot settles.
+  The restart is never synchronous — `apply.sh` is a child of middlewared's
+  own job runner, and later `ix-*` boot units still need midclt. Manual runs
+  of `apply.sh` never trigger a restart.
+
+- **`TypeError: string indices must be integers` when creating a B2 task on
+  TrueNAS 24.10 (Electric Eel)** (#1). The credential schema differs between
+  releases: on 24.10 `credentials["provider"]` is the type string (`"B2"`)
+  with the account/key in `credentials["attributes"]`, while 25.04+ moved
+  them into a provider dict. The injected `get_restic_config` only handled
+  the 25.04+ shape. It now detects the schema and reads the credentials from
+  the right place on both; `create_task.py list-credentials` and `list-tasks`
+  got the same treatment.
+
+- **`create_task.py verify` false-positive after reboot.** `verify` trusted
+  `hook_status.json`, which only records that the files were patched on disk —
+  not that the running process loaded them. `verify` now also compares the
+  middlewared main-process start time against `patched_at` and reports FAIL
+  (with recovery instructions) when the process predates the patch.
+
+### Changed
+
+- README and script comments no longer claim PREINIT runs "before middlewared
+  starts"; the boot ordering and the deferred restart are now documented.
+- `recover.sh` and `uninstall.sh` cancel a still-queued deferred restart
+  before performing their own, and their re-enable instructions now include
+  the required `systemctl restart middlewared`.
+
+---
+
+## v0.0.3 — 2026-06-22
+
+### Fixed
+
+- **`patch/apply.sh` silently killed by the 10-second PREINIT timeout.**
+  TrueNAS PREINIT initshutdownscripts have a 10-second default timeout. The
+  previous apply.sh ran approximately 8 Python subprocesses (each ~1-2 s), so it
+  was routinely killed mid-run. Symptoms: patches not applied after reboot, but
+  re-running `bash apply.sh` manually (no timeout) always succeeded.
+
+  Fix: `install.sh` now registers the hook with `"timeout": 120`. Existing
+  installations are updated to the new timeout on the next `bash install.sh` run.
+
+  Additionally, `patch/apply.sh` consolidates its Python subprocess invocations
+  from ~8 down to 2, reducing startup overhead from ~12-16 s to ~2-4 s — well
+  within the new 120-second budget.
+
+### Changed
+
+- `find_mw_python` in `apply.sh` no longer spawns a separate Python process to
+  verify the interpreter can import `middlewared`. Verification is now implicit in
+  the combined path-discovery subprocess that follows.
