Steps to reproduce:
- Enable “Packaging” in Inventory settings.
- Create a storable product “P1” with:
    - weight: 10 kg
- Create a delivery picking:
    - Add one unit of P1
    - Mark as “To Do”
    - Set quantity to 1 → the move becomes assigned and the picking weight is correctly computed to 10
- Click “Put in Pack” → a package is created with `shipping_weight = 0`, and the picking weight incorrectly computed to 0

Problem:
- `picking.shipping_weight` is computed as: `weight_bulk` + sum(`pack.shipping_weight or pack.weight`) https://github.com/odoo/odoo/blob/17.0/addons/stock_delivery/models/stock_picking.py#L72-L79
- Once the product is placed in a package:
    - `weight_bulk` becomes 0 (because Total weight of products which are not in a package). https://github.com/odoo/odoo/blob/17.0/addons/stock_delivery/models/stock_picking.py#L96
    - `pack.shipping_weight` is 0 on creation.
    - The fallback `pack.weight` is 0 because its compute depends on the `picking_id` in context. Without this context, the compute uses only quants https://github.com/odoo/odoo/blob/f7c033eff7b7bc83d6d18fc5e4df320f43ae5021/addons/delivery/models/stock_quant_package.py#L11-L13

Issue before this commit:
=========================

The high-priority maintenance request count (todo_request_count_high_priority) 
was not calculated correctly.

Steps to Reproduce:
=========================
- Install the maintenance module.
- Create a maintenance request and set the Priority to High (3-starred) in the form view.
- Open the dashboard.
- Observe that the high-priority request count is not displayed.
- The count always remains 0, even when high-priority requests exist.

Cause of the issue:
=========================
In this [PR](https://github.com/odoo/odoo/pull/94866), the logic was mistakenly changed. 
The priority field is defined as a Selection field, but while computing the count, the comparison 
was done against an integer(3, not '3') instead of the actual string value. Since the stored 
value is '3' (string), the condition is always evaluated to False, resulting in a count of 0.

With This Commit:
=========================
Ensure that high-priority maintenance requests are correctly counted and displayed on 
the dashboard when they exist. This provides better visibility of critical requests and
helps users prioritise maintenance work effectively.
