feat(templates): T5 boot seeder + default seeds

TemplateSeeder (OnModuleInit) seeds repo file defaults as global (scopeId NULL) templates if absent. Idempotent per (key,channel,locale,version): re-boot inserts nothing; a bumped version adds a new row and keeps the old for audit. Seeds: welcome (email), payment.receipt (email+sms), onboarding.reminder (email) — placeholder copy for marketing to replace. 3 tests. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
