Bounty #12161 - Improve printer selection UI

Changes

Added static cache for vendor data to avoid repeated JSON loading
Reduces loading time when opening printer selection dialogs
Improves UX by faster dialog response time

Background

The printer selection dialog was slow because it loaded all system models from JSON every time the dialog opened. This PR adds caching to load the data only once.

TODO

Implement lazy loading for large printer lists
Group printers by vendor and series
Add search functionality

This is a work-in-progress PR for the 00 bounty.
