Studio Settings gains a default HST rate; the rate is frozen onto each
payment at booking and computed against the pre-tax subtotal, with the
total billed as subtotal + tax. The rate is overridable per booking on
My Lessons while unpaid (recomputing the tax amount), comped
registrations are never taxed, and receipts break out subtotal/HST/total.

Builds the payments report (roadmap #8) from us_payments: a monthly
per-instructor view with subtotal, HST collected, and grand-total
aggregation, plus a nonce-protected CSV export via admin-post. Studio
admins see all instructors and can filter; instructors are scoped to
their own rows. The Payment Report menu is gated on export_payments so
instructors (who lack manage_billing) can reach it.

## HST / Tax
A studio-default **HST rate** (percentage) is configured on **Studio Settings**
(`us_hst_rate`, `manage_billing`). At booking the rate is **frozen onto the
payment** (`us_payments.tax_rate`) and the tax is computed against the pre-tax
subtotal (`tax_amount = round(amount × rate / 100, 2)`). The billed total is
`amount + tax_amount` (`Payment::total()`). Comped registrations are never taxed
(rate and amount are 0).
The rate is overridable **per booking** on **My Lessons** (instructor) while the
payment is still unpaid; saving recomputes `tax_amount` from the current
subtotal (`PaymentRepository::updateTax`). Receipts break out subtotal, HST, and
total when tax applies.
