YOKO Sanitary Stock - Blade Syntax Fix Report

Checked: all 31 Blade view files under resources/views
Method: Laravel BladeCompiler compileString + php -l on every compiled view
Result after fix: 31/31 compiled views PASS, 0 PHP parse errors

Fixed files:
1. resources/views/warehouse/purchases/form.blade.php
   - Replaced complex @json(...) expression containing nested arrow functions/array literals.
   - Prepared the product/unit payload in an @php block, then passed a simple variable to @json.

2. resources/views/sales/pos.blade.php
   - Replaced complex @json(...) expression containing nested arrow functions/array literals.
   - Prepared unit payload in an @php block using a normal closure.
   - Kept the JSON in a safely escaped data-units attribute.

Original errors reproduced before fixing:
- Unclosed '[' does not match ')' in warehouse/purchases/form.blade.php compiled output
- Unclosed '[' does not match ')' in sales/pos.blade.php compiled output

After fixing: 0 parse errors across all Blade views.
