feat(feishu): interactive approval and question cards with buttons

Render Harness approval and single-choice question interactions as
interactive Feishu cards with approve/reject and answer buttons,
matching the already-available interactionCards behaviour. Cards are now
the default; set DSH_IM_INTERACTION_CARDS=0 (or interactionCards=false)
to keep the plain-text reply flow.

- bridge.mjs: approve:/reject:/answer: card actions, interactionCards
  option, gated approval render hook, interactive question presentation,
  and operationArguments/printableText helpers; refactor the inline
  question answer into #submitQuestionAnswer so both text replies and
  card buttons share one path.
- feishu-cards.mjs: approvalCard (approve/reject) and questionCard
  (option buttons) templates.
- feishu-runtime.mjs: default interactionCards from env (on).
- harness-approval.mjs: optional channel render hook + submitByApprovalId.
- i18n-en: add the new card t() keys.
- Tests: pin the plain-text reply flow in state-machine suites that
  drive it, and add dedicated card tests for the default approve/reject,
  answer buttons, and the text fallback. Full suite shows no new
  failures versus upstream.
