The aim is to have an indicator of entropy during password change

This feature would be exactly the same as the one described and developped in LemonLDAP::NG (using zxcvbn) :

https://gitlab.ow2.org/lemonldap-ng/lemonldap-ng/-/issues/2971

This features depends on #834 for graphic part

Features is nearly finished. TODO:

• ~fix unit tests : https://github.com/ltb-project/self-service-password/actions/runs/8008687127/job/21875651444 (due to autoload not built: should use composer update)~
• ~write unit tests~
• ~add js checks for other password criteria~

[davidcoutadeur]

All jobs in TODO are completed. Seems fine to me. Maybe do some manual tests on platforms with other configuration?

The entropy feature made me code also the other criteria checks.
