Add Paperclip agent activity mirror to case detail page

New "Agents" tab in case detail shows all Paperclip agent comments,
issue status, and agent status for each case — eliminating the need
to switch between Legal-AI and Paperclip UIs.

Backend: 4 new DB query functions in paperclip_client.py (issues,
comments, agents, post_comment) + 2 new API endpoints (GET/POST
/api/cases/{case_number}/agents). Comment posting uses Board API
with DB+wakeup fallback to ensure CEO routing.

Frontend: agents.ts hooks (10s polling), AgentActivityFeed component
(markdown timeline + comment input), AgentStatusWidget (sidebar),
4th tab in case detail page.

Also includes new-company-setup-guide.md documenting the process
for setting up the betterment levy (CMPA) company.
