Port expense report grouped itemized view + i18n + return types from master

Ports the net behaviour from three master commits into v3.0 as a single change, because v3.0 has already diverged structurally (controller moved from V1/Admin/Report to Company/Report, blade has its own CSS rework using the bundled fonts partial, and v3.0's App\Facades\Pdf replaces Barryvdh\DomPDF\Facade\Pdf). The three source commits are: 834b53ea (grouped itemized expenses), e22050bc (DomPDF facade + Pint — adapted to v3.0's App\Facades\Pdf), 0e9f18d4 (expenses.uncategorized + pdf_expense_group_total_label i18n keys + View|Response return type).

Controller: replaces the expenseCategories aggregate fetch with an itemized Expense query ordered by date, groups by category name with expenses.uncategorized fallback, and shares an expenseGroups collection of {name, expenses, total} plus the overall totalExpense. Adds expense_category_id to applyFilters. Updates the docblock return type from JsonResponse to View|Response. Keeps v3.0's App\Facades\Pdf.

Blade: replaces the single expenseCategories aggregate table with a per-group itemized table (date / note / amount columns + per-group total line using the new pdf_expense_group_total_label i18n key). Adds the item-table-* CSS classes and removes the old expense-total-table bottom block.

lang/en.json: adds expenses.uncategorized = "Uncategorized" and pdf_expense_group_total_label = "Group total:".
