Rdzleo c24a9bc162 feat: 集成 dzbj LVGL 显示模块 + 配网模式内存优化

阶段1: 将 dzbj 项目的 LVGL 8.3.11 LCD 显示集成到 AI小智 主项目，
开机显示 ScreenHome 界面，同时优化配网模式下的内存使用，
确保 WiFi+BLE+LVGL 三者共存运行。

## 新增功能

### dzbj 显示模块集成
- 新增 main/dzbj/ 目录，移植 LCD 驱动(ST77916 QSPI)、触摸驱动(CST816S)、
  LVGL 初始化和 SquareLine Studio UI 界面
- I2C 总线共享：dzbj 触摸控制器复用主项目的 I2C_NUM_1 总线
- GPIO 冲突解决：LED(GPIO21)、Touch1(GPIO1)、Touch4(GPIO7) 改为 NC，
  电池 ADC 从 GPIO6 改为 GPIO3
- 添加 LVGL、esp_lcd_st77916、esp_lcd_touch_cst816s 等组件依赖
- managed_components 纳入版本管理

### 配网模式轻量化启动
- BoxAudioCodec: 新增 output_only 模式，仅创建 I2S TX 通道（省 ~13KB DMA）
  跳过 ES7210 ADC 初始化（省 ~2-4KB）
- AudioCodec: 新增 StartOutputOnly() 方法，仅启用扬声器输出
- Application: 配网模式跳过 Opus 编码器、输入重采样器、协议初始化、
  天气位置检测等网络业务
- 板级构造函数: 配网模式跳过电池检测、IMU传感器、PowerSaveTimer

### WifiBoard 配网流程修复
- NeedsProvisioning() 静态方法: 读取 NVS force_ap 和 SSID 列表，
  用于提前判断配网模式
- force_ap 竞态修复: 构造函数不再清零 force_ap，改在 StartNetwork() 清零，
  确保 NeedsProvisioning() 能正确读到 force_ap=1
- Application 缓存 provisioning_mode_ 成员变量，避免重复读 NVS

### BLE 配网重启修复
- 配网成功后用 esp_timer 延迟重启替代 xTaskCreate，
  避免内存紧张时任务创建失败导致设备不重启
- 注释掉 WiFi 连接成功后的 MAC 地址发送步骤

### sdkconfig 内存优化
- BT_ALLOCATION_FROM_SPIRAM_FIRST=y (BLE 动态分配优先 PSRAM)
- SPIRAM_MALLOC_RESERVE_INTERNAL=32768
- NVS_ALLOCATE_CACHE_IN_SPIRAM=y
- WiFi 静态缓冲区数量优化 (RX=10, TX=8)

Tests for LVGL

The tests in the folder can be run locally and automatically by GitHub CI.

Running locally

Requirements (Linux)

Install requirements by:

scripts/install-prerequisites.sh

Run test

Run all executable tests with ./tests/main.py test.
Build all build-only tests with ./tests/main.py build.
Clean prior test build, build all build-only tests, run executable tests, and generate code coverage report ./tests/main.py --clean --report build test.

For full information on running tests run: ./tests/main.py --help.

Running automatically

GitHub's CI automatically runs these tests on pushes and pull requests to master and releasev8.* branches.

Directory structure

src Source files of the tests
- test_cases The written tests,
- test_runners Generated automatically from the files in test_cases.
- other miscellaneous files and folders
ref_imgs - Reference images for screenshot compare
report - Coverage report. Generated if the report flag was passed to ./main.py
unity Source files of the test engine

Add new tests

Create new test file

New test needs to be added into the src/test_cases folder. The name of the files should look like test_<name>.c. The basic skeleton of a test file copy _test_template.c.

Asserts

See the list of asserts here.

There are some custom, LVGL specific asserts:

TEST_ASSERT_EQUAL_SCREENSHOT("image1.png") Render the active screen and compare its content with an image in the ref_imgs folder. If the compare fails lvgl/test_screenshot_error.h is created with the content of the frame buffer as an image. To see the that image #include "test_screenshot_error.h" and call test_screenshot_error_show();.
TEST_ASSERT_EQUAL_COLOR(color1, color2) Compare two colors.

Adding new reference images

The reference images can be taken by copy-pasting the test code in to LVGL simulator and saving the screen. LVGL needs to

800x480 resolution
32 bit color depth
LV_USE_PERF_MONITOR and LV_USE_MEM_MONITOR disabled
use the default theme, with the default color (don't set a theme manually)
