fix: enable Qrevo Master wash/fill dock features (code 14 dock, Roborock QRevo S5A)

[Jason-Morcos]

Summary

Adds RoborockDockTypeCode.qrevo_master_dock to WASH_N_FILL_DOCK_TYPES so dock type 14 is treated as a wash/fill dock.

I noticed that with the HA 2026.7 update, by Qrevo S5A dock stopped showing the tank entities and strainer entity.

Why

HA 2026.7 diagnostics show a Qrevo Master dock reporting dockType: 14, which maps to RoborockDockTypeCode.qrevo_master_dock. The same dock reports wash-capable data, but python-roborock currently excludes it from WASH_N_FILL_DOCK_TYPES, so is_wash_n_fill_dock() returns False.

That causes the V1 wash_towel_mode trait to be skipped. Downstream in Home Assistant, wash_towel_mode is not None gates the clean-water, dirty-water, and strainer entities, so those entities can become stale/restored for this dock even though the underlying dock data is available.

Sanitized diagnostics comparison:

dockType 14: dss=168, strainerWorkTimes=44, wash_towel_mode absent, smart_wash_params absent
dockType 15: dss=169, strainerWorkTimes=34, wash_towel_mode present, smart_wash_params present

Changes

• roborock/device_features.py: add qrevo_master_dock to WASH_N_FILL_DOCK_TYPES.
• tests/devices/traits/v1/test_device_features.py: add a focused regression test proving is_wash_n_fill_dock(RoborockDockTypeCode.qrevo_master_dock) is true.

Pull request overview

This PR updates dock capability detection so RoborockDockTypeCode.qrevo_master_dock (dock type 14) is treated as a wash/fill dock, restoring downstream feature/entity availability that depends on is_wash_n_fill_dock() (e.g., Home Assistant’s wash-related entities).

Changes:

• Add RoborockDockTypeCode.qrevo_master_dock to WASH_N_FILL_DOCK_TYPES.
• Add a focused regression test asserting qrevo_master_dock is recognized as a wash/fill dock.

Thank you for this PR! This has been something on my TODO list for a while now as we handle dock types a little poorly and rigidly. Inspired by this PR, I have actually made a PR that will solve a bit more of the problem at once and add a number of new dock types:

#867

I'm going to close out this PR as mine will handle a bit more, but I sincerely appreciate you making this PR!
