A new shared module centralizes the common logic used by Odoo's document extraction features. This should make invoice, expense, recruitment, and purchase extraction easier to maintain and more consistent without changing the core user workflow.

This commit adds a module that contains the common business logic of all *_extract modules.

The Turkish localization now includes a Profit and Loss report and a translatable Balance Sheet, making financial reporting clearer for Turkish users. The simplified balance sheet was removed because it duplicated the expanded balance sheet view.

* Make balance sheet report translatable
* Add PnL report
* Remove brief balance sheet as it is just unfolded balance sheet

Users can now delete document workspaces that contain documents directly from folder form and list views. The action opens the same confirmation wizard used elsewhere in the Documents app, making workspace management more consistent and reliable.
