fix(bruno): convert drifted body keys to body.data — CLI scenario runs now carry bodies

Follow-up to the sweep route audit, correcting its diagnosis: the CLI
DOES read .yml bodies — via OpenCollection's `body.data` string form
(the NewDevDBSetup script always worked because it used it). The
failing scenario POSTs used `body.json` (structured) / `body.jsonBody`
(string) — keys the CLI silently ignores, sending Content-Length: 0
with form-urlencoded content-type, so every server bind failed.

- 81 bodies converted to data-form (json maps serialized; jsonBody
  strings kept verbatim, {{vars}} intact).
- 6 pre-existing TRUNCATED payloads repaired: the original generator
  cut bodies at the first {{var}} (every SHA-256-identified scenario
  plus Sync Progress/Sync Bookmarks shipped mid-JSON and 400'd from
  day one). Rewritten whole, faithful to each file's documented
  purpose; book_sha256/book_uuid added to the environment.
- environments: opds_base_url correction from the sweep retained.

Verified live against the rebuilt dev container: the full koreader
scenario tree runs green through `bru run` — 14/14 (202s across
immediate/checkpoint/SHA-256 progress, 200s bookmarks, highlights,
notes; SHA-256 book identification exercised against a real
file_sha256).

-  ## Check Registration Status
-
-  Checks the current status of a device registration request.
-
-  **Method:** POST
-
-  **Endpoint:** /api/devices/register/status
-
-  **Authentication:** None
-
-  **Request Body:**
-  - `registration_id` (string): UUID received from registration request
-
-  **Response:**
-  - `registration_id` (string): The registration UUID
-  - `status` (string): Current status
-    - `pending`: Awaiting user approval
-    - `approved`: Registration approved, device ready
-    - `rejected`: Registration rejected by user
-    - `expired`: Registration expired (not approved in time)
-  - `device_name` (string): Name of the device
-  - `device_type` (string): Type of device
-  - `created_at` (string): Registration timestamp
-  - `updated_at` (string): Last status update timestamp
-
-  **Status Codes:**
-  - 200: Status retrieved successfully
-  - 404: Registration ID not found
-  - 400: Invalid registration ID format
-
-  **Polling Recommendations:**
-  - Poll every 5-10 seconds while status is `pending`
-  - Stop polling when status changes to `approved`, `rejected`, or `expired`
