Adds three new tabs to the organisation settings page:
- E-mail opmaak: replaces old EmailBrandingTab to use the new
organisation_email_settings API (logo, colors, footer, reply-to)
- E-mail templates: list/edit/preview/test/reset all 6 template types
with variable hints, defaults comparison, and iframe preview
- E-mail log: server-side paginated table with filters (search, status,
type, date range), status chips, and expandable row details
Supporting files:
- types/email.ts: TypeScript interfaces for settings, templates, logs
- composables/api/useEmail.ts: TanStack Query hooks for all email endpoints
