Events, Agent, and Audit were standalone read-only pages that never
cross-referenced the entity they related to. Fold them into EntityDetail
as entity-scoped cards (Agent activity, Audit trail) alongside the
existing Signals/Executions/Knowledge cards, and give the Signals card
real Ack/Mute/Resolve actions. Signals stays a standalone page since
it's the only one with cross-entity triage value (badge count, actions).
Also fixes the underlying reason those new cards would've stayed empty:
agent_activity rows were never tagged with entity_id at insert time
(cmd/nomos/store.go, internal/mcp/server.go), even though the column
and the API filter both support it. Added a best-effort resolver that
checks common tool-arg keys (target, entity_slug, slug, ...) against
the entities table.
