fix: align portfolio-hub read adapter to live API contract

whoami now hits GET /v1/user_info (the live endpoint; /v1/auth/whoami
does not exist), get_portfolios parses the {portfolios:[...],total} envelope
and filters by managed_by_daemon_id client-side (the list endpoint is
token-scoped, no such query param), and a missing URL scheme now defaults
to http:// so a bare host can't silently degrade the daemon.

 """portfolio-hub read HTTP adapter (REQ-027 AC-1/AC-4).
 
-Mirrors portfolio-hub `list_portfolios_v1`:
-  GET /v1/portfolios?managed_by_daemon_id=<id>
-  GET /v1/auth/whoami        (returns {"daemon_id": "..."})
+Matches the live portfolio-hub HTTP contract:
+  GET /v1/user_info   -> UserInfoResponse {"daemon_id": "...", ...}
+  GET /v1/portfolios  -> PortfolioListResponse {"portfolios": [PortfolioItem], "total": N}
+
+The list endpoint is token-scoped (no `managed_by_daemon_id` query param);
+results are filtered client-side by `managed_by_daemon_id == daemon_id`.
+`PortfolioItem` carries no `active_strategy_id`/`strategy_params`, so those
+default to None/{} (opaque pass-through stays empty until sourced elsewhere).
