refactor: extract formatter and template services

[chhoumann]

Summary

• Adds formatter evaluator boundaries so macro/template/inline JavaScript evaluation is explicit and injectable.
• Extracts folder selection and template file operations into dedicated services.
• Removes remaining direct capture dependencies on the old single-template path and covers preview/append behavior regressions.

Preserve caller title when evaluating TEMPLATE tokens

Using TemplateEvaluator.evaluateTemplateContent(..., templatePath) here makes nested {{TEMPLATE:...}} expansion call setTitle() with the template file name, and because the nested formatter shares context.variables, that title value leaks back into the parent formatting run. In flows where no title was pre-set (for example API format() input that includes {{TEMPLATE:...}} followed by {{TITLE}} or {{VALUE:title}}), the output now incorrectly uses the template basename instead of leaving title unset/derived from the actual target file context.
