The master agent was routing expense/receipt requests to finance_agent
instead of expenses_agent because only DB-registered agents appeared
in get_active_agents(). This adds auto-activation of all in-memory
registered agents with precise capability summaries so the LLM picks
the right specialist.

Routers calling /registry/agents raised AttributeError because
get_all() was not defined. Added method returning all registered
agents with active status, capabilities and instance flags.
