feat: unify all invoice popups to shared InvoiceDetailPopup shell
All invoice popup modals (team invoice, sub-invoice team, client invoice,
external sub-invoice) now share InvoiceDetailPopup + SubcontractorInvoiceDetailView.
Same overlay, header, scroll body, footer action row — just different data per role.
- New InvoiceDetailPopup component (overlay shell, header, scrollable body, footer)
- SubcontractorInvoiceDetailView: respects item._inferredType if pre-set
- ClientInvoiceModal: uses shared components, adds sortable headers
- TeamInvoiceDetailPanel embedded: uses shared components, keeps edit-dates/email/company
- TeamInvoices sub-invoice popup: uses shared components, cleans descriptions
- ExternalMyInvoices popup: uses shared components, fixes detailSort vars (was unused)
