Config & feature flags

A config value only changes behavior when the runtime reads its key. Keys resolve per-tenant override → global → built-in default, and an unset key uses its default (no row needed). Currently wired keys (all bool):

• flag.autonomous_send_enabled (default true) — false holds a tenant's autonomous SMS replies for owner approval.
• flag.website_contact_send_enabled (default true) — false throttles website contact-form auto-replies for a tenant.
• flag.calendar_email_handoff_enabled (default false) — true arms C6e email / contact-form booking offers for a tenant.
• flag.calendar_sms_handoff_enabled (default false) — true arms the C6 SMS booking handoff (also needs Twilio A2P).
• flag.calendar_offer_in_test_mode (default false) — true lets contact-form booking offers fire even while the box runs in test mode, without arming any other autonomous send. Use for "offers only" on real traffic.
• uib.autodraft.email (default true) — false opts a tenant out of the Universal Inbox AI draft-hold on inbound email (the held reply prefilled in the inbox composer for owner Send). Entitlement-gated.
• uib.autoack.email (default false) — true is the operator capability gate for the Universal Inbox first-touch email auto-acknowledgement. The customer-facing ack also requires the tenant's reply posture set to "Auto-acknowledge, hold replies for approval" (approval_mode=INSTANT_ACK_PLUS_APPROVE) — both gates required.

Absent / not set = the default shown above. Other keys can be stored here now but take effect only as more consumers are wired.
