/**
 * Add team assignment notification subtypes and templates,
 * and fix email template brand colors.
 *
 * Creates:
 * - Internal notification subtypes: ticket-team-assigned, task-team-assigned
 * - Internal notification templates for each subtype (7 languages)
 * - Email notification subtype: Ticket Team Assigned
 * - Email template: ticket-team-assigned (7 languages, client-facing)
 *
 * Fixes brand colors in 5 source-of-truth email templates:
 * - projectTaskAssignedPrimary: green (#10b981) button → brand purple (#8A4DEA)
 * - emailVerification: blue (#3b82f6) theme → brand purple/cyan
 * - noAccountFound: legacy gradient (#667eea→#764ba2) → brand gradient
 * - tenantRecovery: legacy gradient (#667eea→#764ba2) → brand gradient
 * - portalInvitation: purple-only gradient → brand gradient with cyan
 *
 * Uses the shared source-of-truth template pattern.
