Enable System Cache Clearing

Both myself and my AI agent are noticing that there appears to be platform memory caching issues where previous version of templates, warnings and system settings being present, this been happening regularly, most recently when attempting to integrate TTS services and copy clean to a new instance of the app where were present templates and data from a non-related app.
Given significant delays in support, Being able to clear system/memory caching might assist in resolving these issues. This has bee systematic over the past weeks and is impeding progress of our development from days to weeks.
