Change in custom-actions was affecting custom-actions in timeline
the issue was introduced with https://github.com/frappe/frappe/pull/16470

* Fallback to insert in realtime if redis conn fails
* Allow List and str inputs for deferred insert API

Blame on the filters would not be maintained since update_modified was
unset. Also, this API allowed those without access to Kanban Boards to
possibly pass "bad" filters and cause system to fail (possible DOS).

Using client's set_value does a better job at tackling this.

Deletion of kanban boards may lead to 404s on clicking on the Kanban
option in the views. This is due to the cache not being synced with the
DB changes. Changed the hook to on_change since it gets triggered even
in db_set.

`kwargs` is used internally while creating EnvironBuilder which eventually builds request object so additional options of request like content_type or mimetype  can be passed via kwargs
