[PM-13876] replace angular validation with html constraints validation (#11816)

* rough-in passphrase validation failure handling

* trigger valid change from settings

* fix `max` constraint enforcement

* add taps for generator validation monitoring/debugging

* HTML constraints validation rises like a phoenix

* remove min/max boundaries to fix chrome display issue

* bind settings components as view children of options components

* remove defunct `okSettings$`

* extend validationless generator to passwords

* extend validationless generator to catchall emails

* extend validationless generator to forwarder emails

* extend validationless generator to subaddress emails

* extend validationless generator to usernames

* fix observable cycle

* disable generate button when no algorithm is selected

* prevent duplicate algorithm emissions

* add constraints that assign email address defaults
