chore(cpn): implement ui bindings to auto widgets and apply to timers

[elecpower]

This PR is based on Phase 1 from Claude analysis of the code base.

Summary of changes:

• add enabled, visible and post changed binds to every Auto widget
• selectively add text and model binds to Auto widgets
• add the same for GenericPanel to support base Qt ui widgets
• add buddy widgets that rely on the parent widget to control enabled and visibility. Benefit is set the rules on the parent and execute once per update cycle then apply results to buddies. Ideal for label and edit widget but use cases where more than one buddy such as modules.
• reduce dependency and overhead of Qt signals and slots by calling auto widget functions directly
• add ItemModelEventHandler class to encapsulate the generic code embedded in every edit panel
• refactor Timer (simpler than TelemetrySensors) editing to demonstrate implementation of the new methodology

Note: there is no noticeable changes for users

My hands are off this now except for bug fixes.
