Require manual confirmation to purge database with purge-db (#6154)

* Require manual confirmation to purge database

* Fix tests

* Rename to `purge-db-force and skip in non-interactive mode

* Do not skip when stdin_inputs is true

* Change prompt to be info logging to ensure consistent output

* Update warning text

* Move delete log after deletion
