Fleet Vehicle Usage

This module adds a new "Usages" section to the Fleet app so you can log every time an employee takes a company vehicle and when it comes back.

• Each usage record has a driver, a vehicle, an optional destination, a company, notes, and a status: New, Reserved, In Use, Returned or Cancelled.
• Records get an automatic reference number starting with FU/.
• Buttons on the form let you Pick (start using the vehicle), Return it, or Cancel the record. Picking and returning automatically fill in the date and time if it is empty.
• Choosing a driver automatically fills in the "Picked up by" and "Returned by" fields with that same person.
• Odoo blocks saving if the same vehicle is already in use by someone else, or if the same driver is already using another vehicle.
• The vehicle form shows a "Usage" button with a counter, and vehicles currently in use display an "In use" badge on the form and in the kanban view.
• The vehicle list can be filtered on "In use".
• The usage list opens by default showing records that are not yet returned, and can be filtered by status or grouped by driver, vehicle, status or picking month.
• A chatter on each usage record keeps a history of changes and lets you log notes or schedule activities.
• Access is limited to Fleet users, with managers able to delete records, and records are separated per company.
