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

- 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
