"Get profile temp" should be replaced with an HTTP endpoint

[thorrak]

Although I don't think users have reported it as an issue, given the concern cited in #758 I anticipate that a profile could retrieve an incorrect profile point, similar to how it could log incorrect points. To avoid this possibility, it makes sense to instead retrieve the profile point from an API rather than trying to pull it directly from the database within the fermentrack script caller
