report_wkhtmltopdf_param

Purpose

Allow Odoo administrators to tune wkhtmltopdf command-line parameters so PDF reports render with the correct layout.

Features

reporting: Lets administrators maintain a default set of wkhtmltopdf switches (margins, zoom, DPI, etc.) applied to every PDF report.
ir.actions.report: Adds per-report override fields so specific reports can inject their own wkhtmltopdf parameters when rendered.
res.config.settings: Provides a settings UI where company managers update and store the global wkhtmltopdf parameter template in system parameters.
