Batch commit of the pending working tree on security/audit-fixes-2026-07. Major areas: - Outbound webhooks / Zapier: schema + signed delivery with retries, public v1 API (REST-hook subscribe/unsubscribe), settings UI, cron drain. - Deploy hardening: email via SMTP2GO (Resend fully removed), verified DB TLS (DATABASE_SSL=require + DATABASE_CA), storage fails loud in production when Spaces is unconfigured instead of silently using ephemeral disk. - Integrations & features (concurrent work): accounting (QuickBooks/Xero), e-signature (DocuSign/Dropbox Sign), PayPal, geocoding/maps, onboarding, expanded legal pages. - DB migrations 0006–0009.
