feat(agents): mirror Paperclip interactions in case page

Surface issue_thread_interactions (ask_user_questions / request_confirmation /
suggest_tasks) directly inside legal-ai's case detail feed so the user can
answer agent prompts without switching to Paperclip's UI.

Backend (FastAPI):
- paperclip_client.py: 4 new helpers — get_issue_interactions (DB),
  respond_to_interaction / accept_interaction / reject_interaction (REST).
- app.py: extends GET /api/cases/{case_number}/agents to include
  `interactions`, and adds POST /api/cases/{case_number}/agents/interaction-response
  routing to /respond, /accept, /reject in Paperclip.
- paperclip_client.py: also pulls existing httpx calls onto the centralized
  pc_request helper (paperclip_api.py) for consistent auth + run-id headers.

Frontend (web-ui, Next.js 16 + TanStack Query):
- agents.ts: Interaction / InteractionPayload / InteractionStatus types,
  useSubmitInteraction mutation hook (invalidates the activity query).
- agent-activity-feed.tsx: InteractionCard renders radio (single) /
  checkbox (multi) for ask_user_questions, accept/reject + reason for
  request_confirmation, task selection for suggest_tasks. Resolved
  interactions show a read-only summary. Cards are interleaved with
  comments by created_at, so the feed reads chronologically.

Paperclip auto-wakes the issue assignee on a successful response
(queueResolvedInteractionContinuationWakeup) — no explicit wakeup needed.
