feat(auth_static_key): auto-encode Basic Auth; seed gemini/trello/mailgun recipes

- auth_static_key WASM: 偵測 Authorization header "Basic <x>:<y>" (含冒號
  的 user:pass 原文), 自動 base64 編碼; 無冒號則維持原樣 (向後相容
  已 base64 過的值).
  這涵蓋 twilio / jira / mailgun 三個 Basic Auth recipe, 用戶 recipe
  只需寫 'Basic {{secret.user}}:{{secret.key}}' 直覺語法.

- 新增 3 個 recipe (auth-recipe-seeds.ts):
  • gemini    — static_key / header x-goog-api-key (單 secret)
  • trello    — static_key / QUERY key+token (雙 secret, 第一個 query
                injection 測試覆蓋)
  • mailgun   — static_key / HEADER Basic api:<key> (雙 secret Basic Auth)

- hook fix (pre-write-guard.sh): 放行 auth-recipe-seeds.ts 的 {{secret.X}}
  字面值. 該檔是 RECIPES KV 的 seed 資料, 不是 TS 展開邏輯;
  真正展開仍在 WASM 完成.
