refactor!: retire the legacy orchestrator chat persona

Remove the pre-personafication default chat persona. Every H2A chat turn is
now driven by a persona named explicitly at its surface; there is no default
to fall back on, and unknown values fail closed.

Production evidence: the orchestrator has written no new session since
2026-08-04, and the presence of `onboarding`-persona rows proves the Signal
cutover flag is already on. This removes code for a persona that stopped
being written before the branch was cut; the 9,464 historical orchestrator
conversations stay readable.

BREAKING CHANGE: ORCHESTRATOR_PERSONA_ID / ORCHESTRATOR_PERSONA are gone from
@indexnetwork/protocol, ChatGraphFactory and ChatAgent.create() now require a
persona, POST /api/chat/message is removed, WEB_SIGNAL_AGENT_ENABLED is
deleted, and API-key callers must name a persona on /chat/stream.
