feat: email notifications on claim approval + OG images for names

ClaimApproved mailable sent when admin approves a claim — dark
themed HTML email with name, next steps, and CTA links. Wrapped
in try/catch so email failure doesn't block approval.

Dynamic SVG OpenGraph images at /names/{name}/og.svg — shows name,
type badge (Registered/Reserved/Gateway/Available), and branding.
og:image meta tag added to name detail pages via @push('head').
