Describe the enhancement

Previously, chamber lighting had a single "dimmed" brightness level controlled by a three-way toggle (Never / Always / On Idle). This made it impossible to independently configure how bright the lights should be while printing versus when the printer is idle. Users printing in a dark room want the chamber well-lit during a print, but dim when idle — and a different brightness again when actively interacting with the printer (opening the door, turning the knob). The old toggle didn't allow this nuance.

A specific use case: you want full brightness when you open the door to check on a print, a comfortable medium brightness while the print runs unattended, and near-off when the printer is idle overnight.

Expected functionality

The lighting settings menu gains three independent brightness sliders, replacing the old dimming toggle:

1. Chamber Brightness — brightness when you interact with the printer (door open, knob turn, touch). Acts as the ceiling; 0–100%.
2. Print Brightness — brightness during an active print when you're not interacting. 0–100%.
3. Idle Brightness — brightness when the printer is not printing and idle. Automatically clamped to not exceed Chamber Brightness. 0–100%.

Step-by-step behavior:

• User interacts (door, knob, touch) → lights jump to Chamber Brightness, stay there for the activity timeout
• Activity timeout expires during a print → lights settle to Print Brightness
• Activity timeout expires while idle → lights settle to Idle Brightness
• Print ends → lights transition from Print Brightness to Idle Brightness on next activity timeout
