This pull request introduces an automated process to periodically update the DGI (Dirección General Impositiva) state for Uruguayan electronic stock pickings, along with improvements to error handling and logging when a picking is rejected. The main changes are the addition of a scheduled cron job, enhanced logging, and user notifications for rejected pickings.

**Automated DGI State Updates:**

* Added a new scheduled cron job (`ir_cron_update_dgi_state_pickings`) that runs every 10 minutes to update the DGI state of stock pickings with electronic documents in the "received" state. (`l10n_uy_edi_stock/data/ir_cron.xml`, `l10n_uy_edi_stock/__manifest__.py`) [[1]](diffhunk://#diff-36f19bab7c2edeb0f43a1db1639b72e8508deed19652e0b1142ebfce688b9d3eR1-R11) [[2]](diffhunk://#diff-370a6cfd5890d6504958deb4a225d69ec84e84fa59deeeb52c96a849f3fdfc22R14)
* Implemented the `_l10n_uy_edi_stock_cron_update_dgi_state` method in `stock_picking.py` to process batches of pickings and trigger itself again if more records remain. (`l10n_uy_edi_stock/models/stock_picking.py`)

**Error Handling and Notifications:**

* Enhanced the `l10n_uy_edi_action_update_dgi_state` method to log rejected pickings and post a message in the chatter to notify users when a picking has been rejected by DGI, prompting manual review and correction. (`l10n_uy_edi_stock/models/stock_picking.py`)
* Introduced logging setup for the module to support the new logging functionality.
