fix(zone-warm): warm 表 UNIQUE KEY + set() 改 upsert + 原子 increment（B1/B3）

Browse Source 
- CREATE TABLE wpdo_warm 的 meta_key varchar(255)→varchar(191)，
  KEY idx_post_meta → UNIQUE KEY ui_post_meta：沒有這個唯一鍵，
  ON DUPLICATE KEY UPDATE 不會觸發，會不斷 INSERT 重複列。
  （既有站台的 ALTER 遷移原本就在 installer:1329，只有 CREATE 落後）
- Zone_Warm::set() 由 SELECT→update/insert 改為 TMDO_DB::upsert()
- 新增 Zone_Warm::increment()：CAST(COALESCE(meta_value,0) AS SIGNED)+N
  原子計數，取代 get()+set() 的 read-modify-write race（A v3.3.3）
- ZoneWarmTest stub 與 ZoneWarmIntegrationTest 建表同步適配
