* feat: set cache keys for 3 days only

* feat: invalidate should set the latest timestamp

* refactor: cache_keys concern

* remove invalidate_cache method
* refactor reset to set to new value instead of delete
* ensure only one event is dispatched

* feat: set expiry to 24 hours

* chore: make expiry 48 hours

* feat: include destroy event

* feat: set expiry to 72 days

* fix: typo

* test: cache update after `touch`
