This change adds a command-line option that can generate default Odoo, nginx, and log rotation configuration files based on the server environment. It helps administrators start with safer, more complete production settings such as workers, proxy mode, and SSL instead of searching for examples manually.

Description of the issue/feature this PR addresses:
[IMP] New command line option to generate default nginx and odoo config file

This update moves certain stock movement checks into the database to make processing faster and more reliable. Businesses should see improved performance during stock operations, especially when handling larger volumes of inventory movements.

The Intrastat invoice report template has been corrected so it is treated as a main report template. This helps ensure the report can be generated and customized reliably where businesses rely on Intrastat reporting.

Odoo no longer manages log file rotation itself because the built-in approach was unreliable in multi-worker deployments. Administrators should use standard operating-system or external log rotation tools, which are more dependable and widely supported.

[It's completely FUBAR when using workers](https://stackoverflow.com/questions/34186774/why-doesnt-timedrotatingfilehandler-work-properly-and-how-to-solve-this-issuer) and properly reimplementing it is not really worth the effort when logrotate and newsyslog and rotatelogs and cyclog/multilog/cronolog and system-managed event logs (syslog & co) exist.
