* Validate APP_KEY
key:rotate command to rotate keys, only rotates validation data for now
* fixes, swapped encrypters, not saving new value to db, check that key exists first
* add confirmation
* Option to generate new key, re-encrypt data and then save it to .env
A lot more text to try to prevent disaster. Print out both keys 1-2 times.
Fix bug in EnvHelper (when key is commented but not empty)
* fix style
* oops, good phpstan
