Address code review feedback: remove duplication, improve type safety, and harden error handling

[Copilot]

Implements 62 actionable code review comments focused on eliminating duplication, improving type safety, and hardening error handling across the codebase.

Critical Fixes

• TasksTable: Remove duplicate color() method call (second call overrode first)
• TasksTable: Remove now-unused getStatusColor() helper

Deduplication

• ReportBuilder: Extract shared formatCurrency() to FormatsCurrency trait (eliminates identical methods in DetailItemsBlockHandler and FooterTotalsBlockHandler)
• Export Services: Unify export() and exportWithVersion() logic via delegation pattern

// Before: duplicate query/logic in both methods
public function export(string $format = 'xlsx'): BinaryFileResponse {
    $contacts = Contact::query()->where('company_id', $companyId)->get();
    // ... duplicate logic
}

// After: single source of truth
public function export(string $format = 'xlsx'): BinaryFileResponse {
    return $this->exportWithVersion($format, config('ip.export_version', 2));
}

Type Safety & Documentation

• ContactsExport: Tighten map() parameter type from $row to \Modules\Clients\Models\Contact $row
• Payment: Update PHPDoc to reflect enum casts (PaymentMethod, PaymentStatus instead of string)

Error Handling & Security

• ReportTemplateFileRepository: Add JSON_THROW_ON_ERROR + JSON_UNESCAPED_UNICODE flags; wrap decode in try-catch
• ReportTemplateService: Log warning on file deletion failures before removing DB record
• FooterQrCodeBlockHandler: Strengthen escaping with ENT_QUOTES | ENT_SUBSTITUTE | UTF-8
• BlockFactory: Switch from new Handler() to app(Handler::class) for container resolution

Configuration & UX

• filesystems.php: Remove public URL from private report_templates disk
• ip.php: Document export_version constraint (1 or 2); add IP_EXPORT_VERSION env support
• DesignReportTemplate: Replace array_merge() with array_replace_recursive() for proper deep config merging
• InvoicesExport: Add explicit date/number column formatting for Excel output
• ListReportTemplates: Add success notification after template creation
• FooterNotesBlockHandler: Translate hard-coded "Summary" and "Terms & Conditions" headings

Code Cleanup

• ListContacts, ListTasks: Remove no-op mutateDataUsing(fn($data) => $data) closures
• HeaderClientBlockHandler: Add @SuppressWarnings(PHPMD.UnusedFormalParameter) for $company parameter

Test Improvements

• ReportRenderingTest: Add PDF signature check (assertStringStartsWith('%PDF-'))
• BlockFactoryTest: Loosen brittle exception message assertion to regex pattern
• BlockDTOTest: Verify deep copy behavior in cloning test (mutate original, assert clone unchanged)

⚠️ Outside diff range comments (1)

Modules/Projects/Filament/Company/Resources/Tasks/Tables/TasksTable.php

22–38: Remove duplicate color() method call on task_status column.

The color() method is invoked twice on the same column (lines 28–30 and 33–37).
The second call overrides the first. Keep the second implementation (lines 33–37) and remove the first.

                 TextColumn::make('task_status')
                     ->label(trans('ip.task_status'))
                     ->badge()
                     ->formatStateUsing(
                         fn (Task $record): string => static::getStatusLabel($record->task_status)
                     )
-                    ->color(
-                        fn (Task $record): string => static::getStatusColor($record->task_status) ?? 'secondary'
-                    )
                     ->sortable()
                     ->searchable()
                     ->color(function (Task $record) {
                         $status = $record->task_status instanceof TaskStatus ? $record->task_status : TaskStatus::tryFrom($record->task_status);
                         return $status?->color() ?? 'secondary';
                     })
                     ->sortable(false),

♻️ Duplicate comments (1)

Modules/ReportBuilder/Handlers/DetailItemsBlockHandler.php

88–93: Duplicate formatCurrency() method — see FooterTotalsBlockHandler.

This helper is identical to the one in FooterTotalsBlockHandler.php (lines 65–70).
Extract to a shared utility to eliminate duplication.

---

🧹 Nitpick comments (selected sample of key entries)

Modules/Projects/Filament/Company/Resources/Tasks/Tables/TasksTable.php

105–121: Remove redundant helper.

After removing the duplicate color() call, getStatusColor() becomes unused and can be deleted.
Keep getStatusLabel() (still used by formatStateUsing()).

---

Modules/Clients/Exports/ContactsExport.php

36: Tighten mapping type.

-    public function map($row): array
+    public function map(\Modules\Clients\Models\Contact $row): array

---

Modules/Clients/Exports/ContactsLegacyExport.php

10–47: Reduce duplication between v1 and v2 exports.

Mapping and headings are identical — extract shared logic to a base or trait.

---

Modules/Clients/Filament/Company/Resources/Contacts/Pages/ListContacts.php

22–24: No-op mutateDataUsing.

This closure returns data unchanged; remove for clarity.

---

Modules/Clients/Services/ContactExportService.php

14–23: Duplicate logic across methods.

Unify export() and exportWithVersion() through a private method to reduce drift.

---

Modules/ReportBuilder/Handlers/FooterTotalsBlockHandler.php

65–70: Extract shared currency formatter.

Both this file and DetailItemsBlockHandler duplicate the same logic.
Move to a shared trait or utility class for consistent formatting.

---

Modules/ReportBuilder/Handlers/FooterNotesBlockHandler.php

33: Translate hard-coded section headings.

Replace:

- $html .= '<h4>Summary</h4>';
+ $html .= '<h4>' . trans('ip.summary') . '</h4>';

and

- $html .= '<h4>Terms & Conditions</h4>';
+ $html .= '<h4>' . trans('ip.terms_and_conditions') . '</h4>';

---

Modules/ReportBuilder/Handlers/HeaderClientBlockHandler.php

24: Suppress unused parameter warning.

Add:

+/** @SuppressWarnings(PHPMD.UnusedFormalParameter) */
 public function render(BlockDTO $block, Invoice $invoice, Company $company): string

---

Modules/ReportBuilder/Repositories/ReportTemplateFileRepository.php

35–41: Harden JSON encoding/decoding.

Use JSON_THROW_ON_ERROR and JSON_UNESCAPED_UNICODE; handle malformed JSON gracefully.

---

Modules/Projects/Services/ProjectExportService.php

14–23: Avoid loading all data into memory.

Use FromQuery or queued exports for scalability.

---

Modules/Payments/Models/Payment.php

21–35: Update PHPDoc for enum casts.

- * @property string       $payment_method
- * @property string       $payment_status
+ * @property PaymentMethod $payment_method
+ * @property PaymentStatus $payment_status

---

Modules/Invoices/Exports/InvoicesExport.php

36–46: Add explicit column formats for dates and totals.

+use Maatwebsite\Excel\Concerns\WithColumnFormatting;
+use PhpOffice\PhpSpreadsheet\Style\NumberFormat;
@@
+    public function columnFormats(): array
+    {
+        return [
+            'D' => NumberFormat::FORMAT_DATE_YYYYMMDD2,
+         ...
