* perf: chain transactions in requests
Breaks console sometimes, don't see as much value TBH

* feat: global `frappe.in_test` flag
* feat: helper utility to toggle `frappe.in_test`
* fix: use `toggle_test_mode` util
* fix: use `frappe.in_test`
* chore: add comment explaining global `in_test`
* chore: ignore commit replacing flag usage
* test: temporarily disable `frappe.in_test`
this worked earlier because flag was set in werkzeug.local which was separate for API test client
* test: add comment explaining change
