Migrate all components and pages to shadcn/ui with DataTable

Replace custom markup across all pages and components with shadcn/ui
primitives (Dialog, Sheet, Select, Card, Tabs, etc.). Add reusable
DataTable component powered by @tanstack/react-table with sortable
column headers and client-side pagination. Introduce TransactionList
with responsive mobile cards and desktop DataTable, dashboard section
customization (DashboardSection, SectionConfigDialog), and settings
API types.
