feat: OSD Wayland adaptation, Bluetooth types, unit tests and AT-SPI tests

[pengfeixx]

Summary

This PR implements OSD Wayland adaptation, Bluetooth type additions, unit tests, and AT-SPI test expectations for dde-shell.

Changes

1. Brightness applet v1→v2 protocol migration — treelandbrightness.cpp/.h, CMakeLists.txt
2. Display mode applet Wayland adaptation — displaymodeapplet.h/.cpp
3. Bluetooth OSD type additions — main.qml, new osd_bluetooth_on.dci / osd_bluetooth_off.dci
4. OSD panel m_osdTimer initialization moved to constructor — osdpanel.cpp
5. Unit tests added — osdpanel_test.cpp, audioapplet_test.cpp, brightnessapplet_test.cpp, displaymodeapplet_test.cpp, CMakeLists.txt updates
6. AT-SPI test expected values — expected_names.yaml

Summary by Sourcery

Adapt OSD functionality for Wayland, add Bluetooth notifications, and expand automated coverage for OSD components.

New Features:

• Add Bluetooth on/off OSD types and icons.
• Add unit coverage for the OSD panel and audio, brightness, and display-mode applets.

Bug Fixes:

• Initialize the OSD panel timer during construction so it is available before panel initialization.

Enhancements:

• Adapt brightness reporting to the Treeland output-manager unstable v2 Wayland protocol.
• Handle display-mode OSD behavior on Wayland by presenting it as unavailable until protocol support is available.

Build:

• Add CMake targets and test registration for the new OSD unit tests.

Tests:

• Add AT-SPI expected accessibility entries for OSD QML elements.

Reviewer's Guide

The PR updates OSD integration for Wayland by migrating brightness to Treeland output-manager v2 and disabling unsupported display-mode actions, adds Bluetooth OSD resources, initializes the panel timer earlier, expands AT-SPI expectations, and introduces standalone GoogleTest/CTest coverage for OSD panels and applets.

File-Level Changes

Change	Details	Files
Migrates the brightness OSD Wayland client from the v1 color-control protocol to the unstable v2 picture-control protocol.	Regenerates and includes the v2 protocol bindings. Renames the control wrapper and updates brightness event/accessor handling. Binds picture control objects from the output manager while preserving read-only brightness reporting.	panels/notification/osd/brightness/CMakeLists.txt panels/notification/osd/brightness/treelandbrightness.cpp panels/notification/osd/brightness/treelandbrightness.h
Adapts display-mode OSD behavior for Wayland environments where display-mode switching is unavailable.	Detects the Wayland platform during applet loading. Reports a disabled state and prevents display-mode actions on Wayland. Initializes the display-mode state explicitly.	panels/notification/osd/displaymode/displaymodeapplet.cpp panels/notification/osd/displaymode/displaymodeapplet.h
Adds Bluetooth OSD type/icon mappings and corresponding accessibility expectations.	Registers Bluetooth-on and Bluetooth-off OSD types in the default QML model. Extends AT-SPI expected element data for OSD windows and applet content. Adds Bluetooth icon assets.	panels/notification/osd/default/package/main.qml panels/notification/osd/default/package/osd_bluetooth_on.dci panels/notification/osd/default/package/osd_bluetooth_off.dci tests/at/spi/expected_names.yaml
Moves OSD timer setup into object construction to make timer-dependent behavior available before panel initialization.	Creates and configures the single-shot OSD timer in the constructor. Removes duplicate timer setup from init().	panels/notification/osd/osdpanel.cpp
Introduces GoogleTest coverage and CTest integration for core OSD panel and applet behavior.	Adds unit and DBus-oriented tests for panel visibility, timers, OSD type changes, and service calls. Adds property, signal, synchronization, and graceful no-backend tests for audio and brightness applets. Adds DPItem and Wayland-related display-mode behavior tests. Adds dedicated CMake targets, protocol generation, dependencies, and test registration.	tests/panels/notification/CMakeLists.txt tests/panels/notification/osd/CMakeLists.txt tests/panels/notification/osd/osdpanel_test.cpp tests/panels/notification/osd/audioapplet_test.cpp tests/panels/notification/osd/brightnessapplet_test.cpp tests/panels/notification/osd/displaymodeapplet_test.cpp
