Add lesson booking registration flow (offering, questions, policies)
Implements #3: students register for a private lesson by picking a slot,
answering the offering's intake questions, and accepting booking-scoped
policies. Payment is a clean seam for #7 (lessons land pending; payment_id
null; instructor confirms via PATCH /bookings/{id}/status).

- Schema: us_lessons += offering_id, recurrence, series_id, payment_id.
- Lesson: new fields + recurrence constants.
- BookingRepository::insertSeries() builds a weekly series sharing a
  series_id; AvailabilityRepository::findUnbookedInGroup() reserves a group.
- RegistrationGate (src/Registration/): validate + record intake answers and
  booking-scoped policy acceptances. Reused by group enrolment (#4).
- BookingEndpoint::book(): offering_id, recurrence, answers,
  accepted_policy_version_ids; single or weekly; records answers/acceptances
  (type lesson).
- GET /policies?scope=booking filter.
- Front-end booking.js: slot -> questions + policies -> submit.
- Wiring: RegistrationGate built in Plugin, passed via RestRegistrar.
- Test-only WP_Error stub in tests/bootstrap.php for gate testing.

# Feature: Lesson Booking
## Overview
Students register for a private lesson by choosing an offering, picking a time (or reserving a weekly slot for the term), answering the offering's intake questions, accepting current policies, and paying. Instructors confirm or cancel from wp-admin or via the REST API. A lesson becomes `confirmed` only once its payment is `paid` (or the student is comp'd).
## Data Model — `{prefix}us_lessons`
| Column | Type | Notes |
|----------------|------------------|-------------------------------------------------------------|
| `id` | BIGINT UNSIGNED | Primary key |
| `slot_id` | BIGINT UNSIGNED | FK → `us_availability.id` |
| `offering_id` | BIGINT UNSIGNED | FK → `us_offerings.id` (the private-lesson type booked) |
| `student_id` | BIGINT UNSIGNED | WordPress user ID |
| `instructor_id`| BIGINT UNSIGNED | WordPress user ID (denormalised for fast queries) |
| `recurrence` | VARCHAR(10) | `single` or `weekly` |
| `series_id` | BIGINT UNSIGNED | Nullable — groups the lesson rows of one weekly reservation |
| `status` | VARCHAR(20) | `pending` / `confirmed` / `cancelled` |
| `payment_id` | BIGINT UNSIGNED | Nullable FK → `us_payments.id` |
| `notes` | TEXT | Optional student notes |
| `created_at` | DATETIME | Insertion time |
## Registration Flow
1. Student opens the page with the `[us_booking]` shortcode and browses the calendar.
2. Student picks an **offering** (a 30 or 60-minute private-lesson type) and a slot.
3. For a `weekly` reservation, the same weekday/time is held for the rest of the offering's term.
4. Student answers the offering's questions (`GET /offerings/{id}/questions`).
5. Student accepts the current published policy versions (`GET /policies`) — required to continue.
6. Payment is taken per the student's billing method (card by default; `pending` for e-transfer; skipped for comp). See `payments.md`.
7. `POST /bookings` creates the lesson row(s) (`status = pending`), records answers and policy acceptances, marks `us_availability.is_booked = 1`, and links the payment.
8. On successful payment (or comp) the lesson is `confirmed` and a receipt is emailed.
9. Instructor sees the booking under **My Lessons** and may update status via `PATCH /bookings/{id}/status`.
## Weekly Reservations
A weekly reservation creates one `series_id` shared across N lesson rows (one per
week in the term) and reserves the matching availability windows. It is billed
**full-term upfront** as a single payment (`billing_mode = full_term` on the
offering).
## REST API
| Method | Endpoint | Permission |
|-----------|-------------------------------------------------|--------------------------------|
| `GET` | `/wp-json/us-scheduler/v1/bookings` | Any logged-in user |
| `POST` | `/wp-json/us-scheduler/v1/bookings` | `book_lesson` |
| `PATCH` | `/wp-json/us-scheduler/v1/bookings/{id}/status` | `manage_availability` or admin |
`POST /bookings` body: `offering_id`, `slot_id`, `recurrence`, `answers[]`
(`question_id` → value), `accepted_policy_version_ids[]`, and payment data
(see `payments.md`).
`GET /bookings` returns the caller's own lessons (student view) or upcoming lessons for the instructor if the caller has `manage_availability`.
Group classes follow the same registration flow but enrol against an offering of
kind `group_class`; see `group-classes.md`.
## Admin Interface
- **Scheduler** (`view_all_lessons` — studio admin / administrators): all upcoming lessons across all instructors
- **My Lessons** (`view_own_lessons`): upcoming lessons for the logged-in instructor
## Frontend Shortcodes
- `[us_booking]` — student calendar + registration flow; requires `book_lesson` capability
- `[us_student_login]` — front-end login form for students
## Implementation
- Repository: `Unsupervised\Schedular\Booking\BookingRepository` (`insertSeries()` builds a weekly series sharing a `series_id`)
- Model: `Unsupervised\Schedular\Booking\Lesson`
- Registration gate: `Unsupervised\Schedular\Registration\RegistrationGate` — validates and records intake answers + booking-scoped policy acceptances; shared with group enrolment
- Admin controller: `Unsupervised\Schedular\Booking\LessonController`
- REST endpoint: `Unsupervised\Schedular\Booking\BookingEndpoint`
- Frontend: `Unsupervised\Schedular\Booking\BookingPage`, `Unsupervised\Schedular\Auth\LoginPage`
> **Payment seam:** payment is deferred to the Payments feature (#7). For now a
> booking is created with `status = pending` and `payment_id = null`; the
> instructor confirms via `PATCH /bookings/{id}/status`. When payments land, the
> pay→confirm + receipt step plugs into this seam. `GET /policies?scope=booking`
> returns just the booking-gate policies the form must collect.
