Users can now create calendar events from project tasks and create project tasks from calendar events. This helps teams coordinate scheduled work and avoid accidentally booking overlapping task and meeting times.

So in this commit did the following changes:
 - allow to create a event from task and vice/versa so that user
   don't schedule an event at the same time as a task you already have.

The Sign app template screens have been streamlined by removing less-used menu options, making advanced template settings easier to reach, and moving field type management into Settings. A new setting lets businesses control who can manage template access, improving administration without cluttering everyday workflows.

- remove the "delete" button with the base.group_no_one gruop from
 the sign.request kanban view (accessible through form if needed,
 and archive should be promoted)

- delete the menu "Properties" on the sign.template kanban dropdown
 (replaced below)

- add a button (secondary) at the right of the "tags" and at the
 left of the "saving" indicator that takes you the form view of
 the template

- remove the "Edit Fields" stat button from the form view of the
 sign.template (I just reversed the logic, you now go from the
 field edition to the advanced properties instead of the opposite)

 - create a new group "Manage template access" that can be enabled
 through the Sign Settings for the whole db have the (remaining)
 fields "group_ids"' and "user_id" of the sign.template model
 visibility be controlled by that group in the template form
 view and in the template edition view

- unhide the tab "Fields" from the debug mode in the view
 sign.template.form

- delete the menu "signature requests items" completely

- remove menu "Field Types", but add an equivalent action
 to access them from the Settings (see screenshot "Field Types")

- add a help string/tooltip on the field "tip" on model
 sign.item.type: "Hint displayed in the signing hint"

The payroll dashboard layout has been refreshed so cards, spacing, and related controls look more consistent across the application. This improves readability and gives payroll users a cleaner, more polished experience without changing core payroll functionality.

Prior to this PR, there was unnecessary scss. Also the design changes make all the dashboard cards consistent with the others and fix the wrong spacing.

Field service users can now enter decimal quantities when adding products to a job, such as litres of oil or hours of cleaning. This makes product usage more accurate by respecting each product’s unit of measure precision, reducing manual workarounds and billing inaccuracies.

Currently, cannot allow entering decimal numbers in 'add products'. Can now be done.

Use Case-

Service of Generator Set

Service Includes- Oiling, Bore Piston Work, Cleaning
Employee- Administrator

Product Configuration- Engine oil => Consumable , UOM - litre , Rounding Precision- 0.001

2- Gaskit- 1
Product Configuration- Gaskit => Storable , UOM - Units, Rounding Precision- 1

3- Cleaning- 5.566
Product Configuration- Cleaning => Service. UOM- Hrs, Rounding Precision= 0.01

A new bridge module prevents Odoo Studio components from loading in the subcontracting portal where they can cause conflicts. This helps keep the subcontracting portal stable while preserving Studio behavior elsewhere.

Creates a bridge module between `mrp_subcontracting` and `web_studio` to solve the incompatibilities between them.
Basically the issue is :
- `mrp_subcontracting` defines a webclient for the portal view. `home_menu` is removed from the asset bundle.
- `home_menu` is required for `studio` and `studio_legacy` services.
- Both of those services are removed from the asset bundle as well to avoid incompatibilities.
- Studio now implements a patch into the `ListRenderer` that adds the `studio` service in it.

So the solution provided here is to remove both the services and the patch from the asset bundle.
