_*= sale_project, sale_timesheet

Added a new *Services & Materials* view to allow users to create additional delivered
flat fees service or consumable product entries directly in a sale order.

This feature allows:
* Creating analytic lines from a sale order for extra services and materials.
* Automatically creating or updating related sale order lines from those
  analytic lines.
* Handling SO line creation based on product expense policy:
   * `cost` → create a new SO line.
   * `sales_price` → update an existing line if available.
* Updating delivered quantities when analytic lines are changed.
* Reverting effect/deleting SO line when analytic lines are deleted.

All analytic lines created from this flow are assigned to the analytic plan
`sale.analytic_plan_sale_orders`, which ensures an analytic account is created
and set on the sale order.

Products with reinvoicing policy `no` will only be eligible for manual delivery.

If a product has reinvoicing policy anything other than `no` it will be eligible
for upselling from our new view, and delivered quantity will be aggregated
from AALs.

If a project is selected on the sale order, the analytic account is deduced from
that project instead.

Added a stat button on invoices to easily view analytic lines linked to that
invoice.

Technical changes:

* Field `timesheet_invoice_id` is renamed to `reinvoice_move_id` as it's not
  timesheet specific anymore.
* Made `product_uom_id` field on AAL compute to make sure we get expected
  `uom_id` on AAL.
* Changed field `order_id` from `related` to `compute` since we need it to work
  as normal m2o in sale.
* Centralized analytic line reinvoicing logic in the sale module.
* Improved `_get_analytic_lines_to_link` to support timesheet-based
  subscriptions with date filtering.
* `qty_delivered` will now be sum of upsell AALs and stock moves(for
   consu products) and recorded timesheet hours(for timesheets).
