feat(server): ServerModule skeleton with shared ServerContext, worker runs engine + outbox relay (B6)

modules/{auth-settings,sources-identity,acquisition-organize,agent} placeholders listed in
SERVER_MODULES; ServerModule registers routes (under /api/v1, authenticated), tasks,
outbox routes, capabilities and background loops. bootstrap() builds ServerContext (db,
config, logger, events, engine, outbox writer, secrets placeholder, settings reader,
capability registry), fills unregistered tasks with stubs and rejects duplicate task or
outbox ownership. worker starts the OpenWorkflow worker, OutboxRelay and module start().
--role migrate also migrates the engine schema; api/worker connect without migrating.
tasks: TaskRegistry.has, migrateEngineSchema.
