[FIX] stock_picking_batch: blurry barcode in report

From the Inventory (stock) application go to Operations>"Batch Pickings"
Create or open an existing Batch Picking and click on "Print".

A report will be generated containing the barcode associated with the
operations. The barcode cannot be read from a barcode scanner because
it's too blurry (probably because of the low quality it contains
an unnatural greyscale).

When this report is generated from the template, a request to generate
the barcode is sent to the controller, which invoke the procedure to
create the png image on the fly with a set of parameters embedded into
the request.
If the width and height parameters are too low the result is a low
quality image, so the solution is to pass higher parameters and then
resize the image via "style" attributes.

Note that the same solution is applied in multiple templates.
