Feat[Jungfrau]: Inject CCVs using RESTful API

Description

Inject CCVs without using calibration_client. This enables more control over injection and better error transparency.

These are the injected CCV report with the current MR: https://internal.xfel.eu/test_calibration/reports/2871

Below is a link to another report trying to reinject the same CCVs.

This MR is addressing this issue:https://git.xfel.eu/calibration/planning/-/issues/182
