This adds a new timesheet synchronization module with an HTML app that can also be packaged as a Chrome extension or Android app. It helps users manage timesheets outside the standard interface and improves reliability by detecting missing server support and showing clearer messages.

Odoo now automatically leaves out special PostgreSQL databases that are templates or do not allow connections. This helps teams keep internal backup or preparation databases from appearing publicly while still allowing safe copies to be exposed when ready.

Automatically ignore template databases identified in Postgres, and databases where connexion is not allowed.
The use case for this is to have a simple means of creating PG databases and not exposing them to the public : set them as templates or disallow connections.
For example on our test server we always restore the backup from the production DB as a template, of which we expose a copy that we do "-u all" on.

The manufacturing by-products feature was migrated to Odoo's newer internal framework. This helps keep the module maintainable and aligned with the rest of the system, with minimal expected change for day-to-day users.
