Add "Your Organization vs. the Network" live stat to admin

New chain.getOrgShare(rootId) + /api/admin/org-share endpoint compute an
org's share of the whole contract by both member count and total POL
paid, from in-memory state. Admin card (default root 21, saved to
config.orgRootId, auto-loads) shows the two headline percentages, a bar,
and the member/POL breakdown. Verified: #21 org = 51.1% of members,
49.5% of POL.
