feat(comments): email the workspace owner and admins when a comment arrives

[ABB65]

E6 gap 2: a new comment arriving in Studio sent no email. A migrated WordPress site had that (moderation mail); a form submission already has it (notifyFormSubmission), comments did not.

What changes

• notifyCommentSubmitted (server/utils/comment-notifications.ts) mirrors the form notifier: owner and accepted admins (listWorkspaceNotificationRecipients) through useEmailProvider (Resend), one mail each, errors swallowed.
• Two templates in the email-templates collection: comment-pending (asks for review) and comment-published (an auto-approved comment is already live). Author, entry, project and the excerpt (400 characters) are HTML-escaped; the link goes to the project, like the form mail.
• Called fire-and-forget after createCommentIfAllowed, so the visitor's response is unchanged whether or not the mail goes out. A honeypot hit, a refused or invalid comment never reaches it.
• Model flag comments.notifications, default on, toggle in Comments Settings (comments.notifications strings), documented in docs/COMMENTS.md.
• resolvePublicCommentContext now also returns the workspace name and slug and the project's repository name.

Decision for the founder

No new plan feature: the mail needs comments.enabled (already required to take comments) and the model flag. Forms gate theirs on forms.notifications; a comments.notifications plan row would be a pricing-page change, so I left it out. Say if it should follow forms.

Tests

• comment-routes integration: pending asks for review (escaped, link, both recipients), auto-approved says published, notifications: false sends nothing.
• comment-types unit: the flag defaults on.
• pnpm test:ci ran on a machine at load ~90, so about 50 unrelated 5 s timeouts (agent, billing, media) hit; the comment and license-parity suites pass (145 tests). CI is the real check for the rest.

ONAY (t6) — 5ccea0c

• Core/ee sınırı: hasFeature kapısı yok, ee importu yok; notifyFormSubmission ile aynı örüntü, çekirdekte.
• Ayar: model patch rotasındaki {...current, ...body.comments} birleşimi + normalizeCommentsConfig ile notifications kalıcı.
• İçerik HTML-escape ediliyor; proje bağlantı rotası mevcut.
• Testler: unit 10/10 dosya 81/81; integration 50 dosya 470 test; nuxt 43 dosya 274 test; eslint + vue-tsc temiz. (Yük kaynaklı zaman aşımları uzun timeout ile tek tek yeniden koşuldu, geçti.)
• Not (bloklamaz): mevcut yorum modellerinde varsayılan açık geliyor; sahip/yöneticiler yeni e-posta almaya başlar.
