Add Roborock Q10 switch entities

[tubededentifrice]

Proposed change

Adds the remaining switch entities for the Roborock Q10 (B01/ss07), following the merged Q10 DND switch pattern. Split out to one platform per PR as requested in #173883; number and image are separate PRs.

• Child lock and dust collection (dock auto-empty) extend the existing RoborockSwitchDescriptionQ10 list — the description's trait type widens from DoNotDisturbTrait to a Q10SwitchTrait union, everything else follows the merged DND pattern (push updates via add_update_listener).
• Indicator / button light: the device never reports the light state, so this switch is write-only — _attr_assumed_state, state only flips after a successful command, and RestoreEntity keeps the assumed state across restarts.

No dependency bump: targets python-roborock==5.25.0, which dev already pins.

Type of change

• New feature (which adds functionality to an existing integration)

Testing

• The Q10 switch tests are parametrized across DND / child lock / dust collection (on/off round-trip through the trait listener, and failure paths asserting the translated error).
• Dedicated button-light tests: starts unknown with assumed_state, on/off round-trip, a failed command not flipping the assumed state, and state restore after a restart.
• The Q10 mock trait in conftest.py gained small reusable helpers (attach_update_listeners, make_q10_switch_trait); the existing DND mock was ported onto them (behavior unchanged).
• test_switch snapshot regenerated (additions only). Full tests/components/roborock suite passes locally (Python 3.14, python-roborock 5.25.0). Ruff, mypy (strict) and hassfest clean.

Checklist

• The code change is tested and works locally.
• Local tests pass.
• There is no commented out code in this PR.
• I have followed the development checklist.
• I have followed the perfect PR recommendations.
• The code has been formatted using Ruff.
• Tests have been added to verify that the new code works.

Pull request overview

This PR adds the remaining B01 Q10 (ss07) switch entities to the Roborock integration, following the previously merged Q10 Do-Not-Disturb switch pattern. Child lock and dust collection are added by extending the existing Q10_SWITCH_DESCRIPTIONS list (the description's trait type widens from DoNotDisturbTrait to a new Q10SwitchTrait union), reusing the push-based trait-listener update model. A separate indicator / button light switch is added as a write-only, assumed-state entity backed by RestoreEntity, since the device never reports the light's state. Test fixtures, parametrized tests, snapshots, translations, and icons are updated accordingly. No dependency bump is included (python-roborock==5.25.0 is already pinned).

Changes:

• Widen the Q10 switch description trait type to a Q10SwitchTrait union and add child_lock and dust_collection descriptions.
• Add RoborockSwitchQ10ButtonLight, a write-only assumed_state switch that restores its state across restarts.
• Refactor Q10 mock traits into reusable conftest helpers, add parametrized/dedicated tests, snapshots, strings, and icons.
