Upgrade/Install: Bring some consistency to installation screen styles.
* Include `forms.css` and `l10n.css`, for consistency with login screen and other admin screens.
* Remove redundant `@import` directives from `login.css` for files already declared as dependencies.
* Adjust margin on password strength meter for consistency with other fields.
* Increase font size for "You will need this password to log in" notice.
* Fix misaligned icon on "Hide" button for the password.
