Phase 3: Typed Vue components in scripts-v2/

Migrate all shared components to TypeScript SFCs with script setup
lang=ts. 72 files, 7144 lines, zero any types.

- components/base/ (42 files): Button, Input, Textarea, Checkbox,
  Radio, Switch, Badge, Card, Modal, Dialog, Dropdown, DatePicker,
  TimePicker, Money, FileUploader, Select, Icon, Loader, Multiselect,
  TabGroup, Wizard, CustomerSelect, ItemSelect, CustomInput, alerts,
  status badges (Invoice/Estimate/Paid/RecurringInvoice), List/ListItem
- components/table/ (3 files): DataTable, TablePagination
- components/form/ (4 files): FormGroup, FormGrid, SwitchSection
- components/layout/ (11 files): Page, PageHeader, Breadcrumb,
  FilterWrapper, EmptyPlaceholder, ContentPlaceholders, SettingCard
- components/editor/ (2 files): RichEditor with Tiptap
- components/charts/ (2 files): LineChart with Chart.js
- components/notifications/ (3 files): NotificationRoot, NotificationItem
- components/icons/ (2 files): MainLogo

All use defineProps<Props>(), defineEmits<Emits>(), typed refs,
and import domain types from types/domain.
