Polish My Account templates with Bootstrap 5 patterns

Redesign navigation with endpoint icons, offcanvas-lg responsive
pattern, and sticky sidebar. Replace flat dashboard with card-based
welcome greeting (avatar) and quick-action grid. Wrap all forms
(edit-account, edit-address, lost/reset-password) in card sections
with icon headers. Restructure view-order with summary card and
status badge component. Override WooCommerce's float-based layout
and max-width constraint to let Bootstrap flex grid handle sizing.
