Project teams can now view and manage task dependencies directly in the Gantt chart, including dependency arrows, milestone markers, and easier task resizing. When task dates create scheduling conflicts, related tasks can be automatically rescheduled based on working calendars, reducing manual planning effort.

## PURPOSE

It is easier to organize a project and its various task dependencies when we can visualize and manage them from the Gantt view directly.
In addition, auto-shifting tasks' timelines when there is an inconsistency makes the scheduling easier. The user doesn't have to update manually the dates of each task when one of the tasks from the dependency chain is rescheduled.
At last, an indication of the project milestones in the Gantt view helps organize the planning accordingly.

## DETAILS

    - Perform general design changes in web_gantt to lighten the UI
    - Add dependency creation/deletion from the Gantt view
    - Display project milestones in Gantt view
    - Automatically reschedule tasks when changing dependent tasks planned dates implies a conflict.

Warehouse teams can now process wave pickings directly from the barcode interface, helping them handle grouped picking operations more efficiently. This adds dedicated screens, data, and workflow support so staff can scan and manage waves in the same mobile-friendly flow used for other stock operations.

Spreadsheet cells now show the first digits of numbers when the full value does not fit. This makes cropped numerical data easier to read and helps users identify important values at a glance.

When a numerical value is cropped, its first digits are the most
relevant to display.
This commit ensures that we align the text to the left when it's length
overflows from the cell width.

Planning users now get clearer scheduling information before saving shifts, including immediate conflict warnings, allocated hours in Gantt cards, and clearer time-off dates. The update also improves staffing searches by work address and employee skills, making it easier to find suitable people for shifts.

Generic planning improvements:
- Display shifts conflicts directly instead of after record creation
- Display allocated hours in the gantt view's pill title
- Allow looking up slots in function of work address and skills
- Change time off conflict display to indicate the date of the time off
  instead of the overlapping interval
- Change `effective_hours` to be displayed in a smart button
- Allow translation on `planning.role .name`

The Field Service report module now correctly loads the access permission file needed for project sharing. This helps ensure shared projects have the intended permissions available when the module is installed or updated.

Before this commit,  the `ir_model_access.xml` created in the #19483 PR
is not imported in manifest file of the module.

This commit adds this file in the manifest file to have the
`ir.model.access` useful for the project sharing feature.

The app menu logic has been moved into a shared web component so it can be reused by more navigation features, including the command palette. This helps keep menu behavior consistent across the interface while reducing duplicated internal code.
