fix(phpstan): improve typehints and resolve phpstan errors

- Added spaces in typehints for readability
- Added `@phpstan-ignore-line` for DEVELOPMENT condition in `setFieldsToAllProducts()` to mitigate
stan error
- Cast `max_execution_time` to int before calling `set_time_limit`
- Typecast integer variables to string in `str_pad` in `execute()` in GenerateProductCache.php for
PHP compatibility
- Added a check for `getCustomDataEntry` method existence before using it in `updateProductPrices`
in UpdatePrices.php for run-time safety.
