test: 建立 phpunit 測試基建並移植 25 個 HivePress 測試

AddOn 先前 tests=0。新增：
- composer.json（dev 依賴 + phpunit/phpcs script）
- phpunit.xml（failOnWarning=true）
- tests/bootstrap.php：直接 require 核心 plugin 的 unit bootstrap，避免複製
  ~700 行 WP stub，再載入本 AddOn 的類別；補 trait wrapper 與自動 WPDO_ alias
  （includes/back-compat-aliases.php 掛在 plugins_loaded:7，PHPUnit 下不會跑）
- tests/unit/ 25 個測試 + WpdbMockTrait（自 A 移植）

生產碼一併修對外契約：interface-tmdo-hp-adapter.php 改為先宣告空的
WPDO_HivePress_Adapter、再讓 TMDO_HivePress_Adapter extends 它（PHP 無法
class_alias 介面，只有繼承能讓 instanceof WPDO_HivePress_Adapter 對
implements TMDO_ 名稱的 adapter 成立）。與核心 interface-entity-adapter.php
同一模式。這也讓第三方自訂 adapter 用舊介面名仍可通過核心檢查。
