This update adapts the French financial reporting process to changes in how data is exported from Odoo. Instead of downloading entire files, data is now streamed to the user, improving efficiency and reducing download times. This ensures accurate and timely reporting for French customers.

This commit aims to adapt the usage of 'account.fr.fec' to the changes made in community.

In particular `fec_data` field is not used any more. and we use `_get_fec_stream` to stream the content of the file.

This update adds a mechanism to allow other Odoo modules to adjust timesheet values directly within the timesheet wizard. Previously, timesheet adjustments were limited. This enhancement provides greater flexibility for managing timesheets across different workflows and integrations.

Add a hook in helpdesk_timesheet timer wizard for other modules to modify timesheet values.
