Remove YAML configuration support for IQVIA

[bachya]

Breaking change

Per ADR-0010, IQVIA can no longer be configured via YAML and must be configured from the UI. Existing IQVIA users have already had their integrations imported and only need to remove IQVIA-related items from configuration.yaml.

Proposed change

We deprecated monitored_conditions YAML support for IQVIA in 0.107.0 and were schedule to remove it in 0.114.0. Since ADR-0010 was approved in the intervening time, this PR goes a step further by removing YAML configuration support for IQVIA.

Additionally, the IQVIA config entry was using a lot of old code; this PR brings it to modern standards.
