This change adds an initial Customer v2 UI by introducing a generic table component suite, chart utilities, and a detailed customer feature–usage table complete with pagination, sorting, and filtering. It significantly expands the codebase (+3510 lines) and provides reusable UI primitives for richer data presentation on customer pages. Concerns include the lack of accompanying tests or CI validations, potential performance and accessibility issues, and risks around integrating such a large diff without incremental review.
