Add accounts UI with list, create, edit, detail tabs for all sub-entities

Accounts list with paginated table, search, sort. Account detail page with
tabs for members, payment methods, tax exemptions, and processor links.
All sub-entities have create/edit dialogs and delete actions. Forms use
shared Zod schemas via react-hook-form.
