Add pattern attribute to password fields for better compatibility

Problem/Motivation

The Password Policy module is responsible for defining password constraints, but the password input fields themselves don't communicate these constraints to the browser or other applications like password managers.

According to the MDN documentation for <input type="password">, using the pattern attribute is a recommended way to provide validation hints. This allows password managers, such as 1Password, to better understand and validate generated passwords against the policy requirements.

Proposed resolution

Add the pattern attribute to all elements when a password policy is enabled. The value of this attribute should be a regular expression that accurately reflects the constraints defined by the active password policy.
