feat(campaign): default the quote wall on for every campaign

[yingshinlee]

過渡決定:先取消「只有七日書」限制,讓所有活動都能上金句牆。

• migration:把 enable_quote_wall 預設改 true、現有活動全設 true。
• 不動 OSS(豆泥正在重寫 OSS);也不動前端(#5976 已在讀這個旗標 → 全 true → 每個活動文章都顯示上牆鈕)。
• per-campaign 旗標保留,當作日後掛勾:之後要做七日書專屬,可(a)程式碼判定(名稱/shortHash)或(b)等新 OSS 接這個欄位,皆無需改 schema。

base=develop→ICU。
