Add Quoya M515EGBZTN support and fix curtain_motor position inversion

[ErnieV]

Summary

Adds support for the Quoya M515EGBZTN Zigbee roller blind / plissé motor and fixes two existing issues in the curtain_motor driver.

Tested on Homey Pro (Early 2023), firmware 13.2.1-rc.4, with two M515EGBZTN devices running simultaneously.

Closes #1405

Changes

New fingerprints

• _TZE200_gubdgai2 — Quoya M515EGBZTN
• _TZE200_vdiuwbkq — Quoya M515EGBZTN (alternate)

Bug fix: position inversion in setPosition

The device uses 0 = fully open, 100 = fully closed, opposite to Homey's windowcoverings_set (0 = closed, 1 = open). updatePosition already handles this correctly with 100 - value, but setPosition was not inverting — so setting the slider to 0% sent 0 to the device, which opened the blinds instead of closing them.

// before
pos = reverse ? 1 - pos : pos;

// after
pos = reverse ? pos : 1 - pos;

This bug likely affects other TS0601 curtain motors with the same 0=open convention.

Upper/lower limit support (DP 16)

Exposes the device's physical end-stop programming via DP 16 (border):

Enum	Action
0	Set upper limit at current position
1	Set lower limit at current position
4	Remove both limits

• Three flow action cards added via driver.flow.compose.json
• Three checkbox settings added to the device settings screen as a direct alternative to flow cards (Homey has no button type for device settings; the checkbox resets itself after firing)
• Flow card listeners use args.device pattern to correctly support multiple curtain motor devices

Test plan

• Pair a _TZE200_gubdgai2 or _TZE200_vdiuwbkq device — should be recognised as curtain_motor
• Slider at 0% closes the blinds, 100% opens them
• "Reverse direction" setting still works correctly
• Set upper limit: move blinds to desired top position → tick checkbox in device settings → motor stores position
• Set lower limit: same for bottom position
• Remove limits: clears both end stops
• Flow action cards appear in Homey flows for the device
