fix: XLight/Cicero filter wheel integration

[Alpaca233]

Summary

• Use emission_filter_position directly from channel config instead of broken wavelength-to-position mapping
• Only create emission/dichroic dropdown widgets when hardware supports them (fixes orphan widgets on Cicero)
• Use sleep_time_for_wheel for serial communication delays (fixes timeout errors)
• Add XLIGHT_EMISSION_FILTER_POSITIONS config (5 for Cicero, 8 for XLight V3)
• Improve serial response mismatch logging

Test plan

• Test with Cicero hardware - verify emission filter wheel works
• Test with XLight V3 hardware - verify both emission and dichroic wheels work
• Verify no orphan dropdowns appear in spinning disk widget

Pull request overview

Improves CrestOptics X-Light / Cicero spinning-disk integration by aligning UI and live control behavior with the actual hardware capabilities and by making serial timing/logging more robust.

Changes:

• Updates the spinning disk widget to only create/connect emission/dichroic wheel controls when the connected hardware reports those capabilities.
• Switches LiveController emission filter control to use emission_filter_position from the active channel configuration (removing the old wavelength→position mapping).
• Uses sleep_time_for_wheel for XLight wheel serial read delays and improves serial response mismatch logging; adds XLIGHT_EMISSION_FILTER_POSITIONS config.

set_emission_filter() still hard-codes valid positions to 1–8, but the UI now uses XLIGHT_EMISSION_FILTER_POSITIONS (and _def.py documents 5 positions for Cicero). This means a misconfigured emission_filter_position > XLIGHT_EMISSION_FILTER_POSITIONS will pass validation and be sent to hardware, likely causing timeouts/misbehavior on 5-position devices. Consider validating against XLIGHT_EMISSION_FILTER_POSITIONS (or a device-specific max detected at runtime) and updating the error message accordingly so invalid configs fail fast.
