Subject: [PATCH] fix: move export serialization to template-store.js

Adds exportTemplates() to modules/template-store.js, consolidating the
export payload schema (version, schemaVersion, exportedAt, templates) and
field sanitization into the service layer. handleExport() in options.js
now delegates to exportTemplates() and only handles DOM/download logic.

Fixes JuliaKalder/TemplateWing#127
