Purpose
=======

The goal is to review the information displayed in the project updates side panel and also completely review the project profitability calculation.

## Implementation details

### Review the profitability section

In this section (added in community version), the subscriptions are takken into account in the revenues table shown for the project profitability.
With Field Service, the 'Extra Quotations' feature is also takken into account in the project profitability by adding the extra sales orders created with this feature.

### Budget section

This section will list all of budgetary positions linked to the AA of the project. Each row will shown:
- the Budgetary position name
- the allocated amount represents the planned_amount of budget lines
- the spent amount represents the practical_amount of budget lines
- the remaining amount represents the difference between the allocated and the spent amounts

if there are no budgetary positions, an 'add budget' button will be displayed that should open the budget form view (only visible if the user has accounting > accountant access right level).

### Additional changes in the right side panel

- remove the following stat buttons: subscriptions, budget.

codes are reused and shorter
the UI is more user-friendly
some `const self = this` are removed
a new file backend/PDFIframe.js is created for shared logic between
 1. editing sign.template from backend
 2. signing sign.request from backend
Now edit while signing allows
 1. once the signatureItem is dropped, it can be moved to another page.
 2. the dotted lines while dragging the signatureItem is available
 3. when drop an initail signatureItem, `add once` and `add to all pages` are available

Multi select feature is improved for sign.template
New behavior: click sign.item => open popover
click + ctrl sign.item => close all popover + multi-select

Before this commit:
the trigger (ctrl + left click) for edit while signing invalid for MacOS
duplicated code exists for edit while signing logic
some UI features for sign.template don't work for edit while signing
(e.g.
1. once the signatureItem is dropped, it cannot be moved to another page.
2. the dotted lines while dragging the signatureItem is not available
)
Using ctrl cannot multi select sign items

PURPOSE
Various UI improvements to the appointment module on both ends

SPECIFICATIONS
* Reorganize Appointment Type form view fields, also adding a simple interface
  to edit followers of appointment types and related events.
* Set 3 default reminders and enable users to update them. These will be
applied to new events booked from the frontend or backend.
* Customize Front End creation/edition:
  * Update New Appointment Type modal, add default slots and self as user
  * Allow edition of appointment type title, duration and location
  * Add a few placeholders
* Change kanban view to a list when not grouped, similar to Survey's
* Improve sharing modal
* The notifications for appointments created and cancelled/Archived is also
updated such that
  * OdooBot sends notifications instead of a "Public User"
  * Notifications are sent when an attendee cancels but the meeting is not
  canceled because there are still 2+ attendees
  * Public user is no longer a follower

NB
The appointment type location is now set as a partner (see Event.Event Venue).

MISC
Some tests are included.
