fix: LED override, Material Station on the Creator 5 series, camera switch (v1.3.2)

[GhostTypes]

Ships 1.3.2. Requires flashforge-python-api>=1.3.2 (published).

Fixes

• The LED switch is no longer greyed out on every printer. The "Always show LED switch" option was passed to the library as led_control_override using its unset value False. That parameter is tri-state — None means "no override", True forces the capability on, False forces it off — so with the option off (the default) the integration vetoed the printer's own correct capability report on every model. It now sends None when off. Diagnosed on a Creator 5 Pro, where /product reported lightCtrlState: 1 all along.
• Material Station entities now appear on the Creator 5 series. The slot swatches and the active-slot sensor were gated on has_matl_station, a raw /detail passthrough the Creator 5 never sends. Fixed upstream in the library (1.3.2), which derives the capability from the slot data; the manifest floor moves accordingly.
• Capability-gated entities are no longer decided once at setup. They are also added when their capability first appears on a later refresh — platform setup can run before the printer has reported one, and the first refresh may fail outright.

Changed

• The camera switch is no longer created on the Creator 5 series. Hardware testing confirmed streamCtrl_cmd returns success and does nothing there, and cameraStreamUrl stays populated so the switch snapped back to on on the next poll. Inert and un-toggleable, so it is now omitted entirely rather than shipped as a dead control. The camera entity is unaffected. Refs Camera switch permanently unavailable on Creator 5 Pro (availability gated on is_pro instead of is_creator5_pro) #17.

Notes

• Check code not working. #18 (check-code reports) should be resolved by the library fix in 1.3.2, but stays open until the reporter confirms on real hardware.
