Add editable, previewable payment-due email template

The "Payment due" notice the daily billing scan sends was fixed wording baked into PaymentDueMailer. Studio admins can now view, edit and preview its subject and body under Studio Settings -> Payment Due Email. - PaymentDueEmailTemplate stores subject/body/item-line as us_payment_due_email_* options, each falling back to the built-in default when blank, and renders via {token} substitution. - PaymentDueMailer now builds a token map from the same consolidated items/credit/e-transfer/reference data and renders the stored template; the default template reproduces the previous wording exactly. - PaymentEmailController serves the view/edit/save/reset admin page (manage_billing, nonce-checked) with a server-rendered sample preview. - PaymentEmailPreviewEndpoint (POST us-scheduler/v1/payment-email/preview, manage_billing) + payment-email-admin.js drive a live preview of unsaved edits. - Submenu wired under Studio Settings; endpoint wired in RestRegistrar. - Bump to 1.6.0 and add CHANGELOG entry. New options default gracefully, so existing sites need no migration and send the identical notice until edited. Co-authored-by: anthropic/claude-opus-4-8

+### Added
+- **You can now read, rewrite and preview the "Payment due" email, on Studio Settings → Payment Due Email.** The notice a family gets when the daily scan finds lessons to pay for was fixed wording baked into the plugin; now its subject and body sit in an editor you can change to match how your studio talks to its students. Drop in `{student_name}`, `{items}`, `{total_due}` and the rest wherever you want them, and a preview below fills those tokens with sample values and updates as you type, so you see the actual email a scan would send before you save. Leave a field blank to fall back to the built-in wording, or use the reset button to restore all of it at once. Nothing about how or when the email is sent changes — only what it says — and until you touch it, students receive exactly the notice they always did.
