Changes

This PR fixes 3 issues found when running through the test script for the API usage alerting / billing (see script here).

The 3 issues fixed are:

1. The identifier used for retrieving flags from Flagsmith used the organisation name, which can include spaces and therefore was not valid. This PR removes the organisation name altogether because it's not needed and, in fact, would have caused issues if orgs changed their name.
2. The task to update influx data in the sales dashboard was broken due to a KeyError because the range bucket mappings needed updating to account for the new date_start logic when querying Influx.
3. get_client method is currently failing in the task processor since none of the required environment variables are set. I've added these environment variables in now.
