Implement Phase 6 & 7: My Account and Order Details templates (Bootstrap 5, HPOS)

Phase 6 - My Account (15 templates):
- Account layout with sidebar navigation (list-group) and content area
- Orders table with status badges, pagination, and responsive design
- View order with order notes as list-group items
- Address cards with edit/add buttons
- Login/Register side-by-side card layout
- Account edit, password change, downloads, payment methods forms
- Lost/reset password forms and confirmation

Phase 7 - Order Details (5 templates):
- Order details table with items, totals, and customer note
- Line item rows with refund quantity display
- Customer billing/shipping address cards
- Order tracking form
- Order again button

All order templates use WC_Order object methods only (HPOS compatible).
Bootstrap 5 components: cards, tables, list-groups, badges, forms, alerts.
