Credential management for Z-Wave locks

[jlpouffier]

Problem statement

Right now, Home Assistant doesn't have an easy, built-in way to manage things like PINs and user codes for Z-Wave smart locks. This forces people to use third-party app (the vendor's app) instead of a smooth, native system, which makes the whole experience clunky and confusing for new users.

The idea of this bet is to build upon the Matter implementation proposed here #69

In scope

• CRUD (Create, Read, Update, Delete) actions for PINs and user codes.
• Credentials are tied to the lock itself, not to a Home Assistant user.
• Manage everything from the device page and show events in the device activity log.
• Allow codes to be enabled or disabled without having to delete them.

Out of scope

• Create and manage user profiles centrally in Home Assistant, similar to how Apple Home does it, and assign credentials to multiple devices from that profile.
• Link a credential such as a PIN or fingerprint directly to a Home Assistant user so it can be managed across devices.
• Features like scheduling and syncing codes across multiple devices are optional. For now, the focus is on the basics: core create, view, update, and delete actions, plus a device-centered experience.
