Server generated links can contain multiple forward slashes

[paul121]

If settings.SERVER_HOST contains a trailing forward slash then links a generated with a duplicate forward slash, breaking the link. I've seen this for authorization links, registration links and reset password links in utils.py :

farmOS-aggregator/backend/app/app/utils.py

Lines 184 to 185 in 8285090

	server_host = settings.SERVER_HOST
	link = f"{server_host}/authorize-farm/?farm_id={farm_id}&api_token={token.decode()}"

It may be easiest to validate settings.SERVER_HOST to always have a trailing /. Then we can use urllib.parse.urljoin(base, url) to build the link.
