feat: add email-api-data project with EmailTemplates repository and service
New data project owning the emailApi schema: - EmailTemplateEntity with Key, Language, Value, Description, UpdatedAt, OperatorCopy - EmailApiDbContext (schema: emailApi, custom migration table _EmailApiMigrations) - IEmailTemplateRepository / EfEmailTemplateRepository (scoped) - IEmailTemplateService / EmailTemplateService (singleton, 10-min cache) - GetOperatorCopy falls back to first non-empty OperatorCopy across all rows - Initial migration CreateEmailTemplates: creates table + seeds all email.* templates (match + search-results in en/ro) and html-shell fragments with OperatorCopy = "contact@myai.ro" for addressable rows Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
