This change adds dedicated tests to ensure SMS and mail features continue to work well when all related mail capabilities are enabled. It also adjusts payroll test expectations after recent mail notification changes affected internal performance counters.

CRM can now replace broad, generic activity options with more specific ones tailored to the customer record being handled. This helps users pick the right follow-up action more easily, such as CRM-specific email activities, while related mail setup data was reorganized for easier maintenance.

The manufacturing work order form now labels by-products more accurately instead of referring to them as finished products. This small wording change helps users better understand what they are viewing or recording during production.

Invoices created through the Upload button now correctly identify the uploaded file as the invoice’s main attachment. This ensures OCR processing sends the right document for automated invoice reading, reducing failures or manual follow-up.

When creating invoices via the 'Upload' button, the
'message_main_attachment_id' field wasn't set on the record. This
happened because the message posted in the chatter was linked to the
wrong 'res_model' which prevented it from being selected as the main
attachment.

This was causing a bug in the OCR module ('account.invoice.extract')
where we use this field to determine which attachment must be sent to
the OCR server.

The tablet work order screen has been improved to prevent flickering when users enter or update serial and lot numbers. This makes shop floor data entry more stable and less distracting for manufacturing operators.
