To reproduce:
1. Sync the IoT with a 17 database
2. Once it is set up, force shut down the server by Ctrl+C 2 times
3. Wait a few seconds:
=> crash of `WebsocketClient` thread with the following traceback:
```
Traceback (most recent call last):
File "/usr/lib/python3.11/threading.py", line 1038, in _bootstrap_i>
self.run()
File "/home/pi/odoo/addons/hw_drivers/websocket_client.py", line 83>
self.ws.run_forever()
File "/usr/local/lib/python3.11/dist-packages/websocket/_app.py", l>
raise WebSocketException("socket is already opened")
websocket._exceptions
WebSocketException
socket is already opened
```
The IoT synchronised servers can stop in 2 ways that we need to handle:
A. Gracefully (Ctrl+C):
In this case a disconnection signal is sent to the IoT-box
The websocket is properly closed, but it needs to be established a new connection when
the server will be back.
Solution: `while True` loop as `run_forever` will return on close.
`time.sleep` for the reconnection delay
B. Forced/killed (Ctrl+C 2 times):
In this case there is no disconnection signal received
Solution: use `reconnect` that will automatically take care re-attempting a connection
This will also happen with the graceful quit as `reconnect` will trigger if the server
is offline while attempting the new connection
In both case, we perform a reconnection attempt with a delay of 10 seconds to avoid
spamming the database
After this commit:
The websocket will reconnect itself automatically after 10 seconds
if the connection is disrupted

Before, the websocket client was built manually, usign string
concatenation.
Now, urllib.parse() is used to appropriately adapt the database URL.
This update enhances security.

Previously, there was a function called 'start_client' that was invoked
by the 'run' function. As 'start_client' was solely invoked within 'run'
and served no additional purpose, its functionality has been incorporated
directly into the 'run' function.

Before, the url was built with string comprehension.
Now json.dumps is use to ensure that the JSON sent is
valid

-Implemented a WebSocket service to facilitate communication with the IoT box. This enables printing reports on a network different from the browser. Before it was a long polling connection
-Implemented the ability to link multiple printers to a single report. Before it was possible to link only one printer er report
-When multiple printers are linked, a pop-up will prompt the user to select the preferred printers.
-The user's printer selection will be stored in the browser's local storage.
-Additionally, a reset button has been added to clear the printer selection.
