The appraisal interface is streamlined to reduce clutter and make important statuses easier to understand. Users see clearer appraisal cards and landing pages, with low-value meeting, ready, and cancelled indicators removed to make day-to-day appraisal management simpler.

- make landing screen more clear by removing the searchpanel
- change the ribbon color code to be expressive
- Remove the cancel state as it does not have a real meaning in the appraisal case and the ralted demo data to show the action
- clean up the kanban card by removing thr meeting line and move the activity to right
- remove meetings stat button as it does not add real value just more complexity
-  remove the Ready indecation and it also does not add any real value

The Gantt view now shows either the expand or collapse rows button, instead of both at once, with clearer icons. This makes row controls easier to understand and keeps row expansion behavior more consistent with other list-style views.

We make only one of the buttons "Expand rows"/"Collapse rows" appear and use
different icons. Now the button "Collapse rows" only appears when no row is
folded. For this to work correctly, we have to clear more often the set
closedRows. Roughly speaking, we clear that set in such a way that an automatic
expand happens when it would happen in similar situations in the list view.

Project, Tasks, Sales, Helpdesk, CRM, Field Service, Purchase:

1. add a new item in the action menu: "Add/remove followers";
2. pop-up with add (default)/ remove as boolean and a multi-selection field for followers;
3. provide a notify option for the user if adding followers;

Accounting menu actions now display clearer navigation paths, making it easier for users to understand where they are and find key accounting reports or actions. Product screens are also cleaned up by hiding UrbanPiper-specific fields unless they are relevant, reducing clutter for most users.

Added path for the main actions of Accounting (linked to menu mainly)
And clean the default product view (pos_urban_piper fields should not be visible by default everywhere)

The time off request screen has been reworked to make request unit choices clearer and more consistent. This improves the employee experience when requesting leave and helps payroll, planning, projects, and timesheets process those requests more reliably.

The signing document viewer has been visually improved to reduce overlapping controls and make the signing flow easier to use. The side panel now appears on the right and selects the first option by default, helping users preview and complete documents more smoothly.

**Purpose
========**
This PR handles overriding the default PDF.js viewer styling to enhance the user experience while signing documents. 

Specifically, it addresses the issue where overlapping elements, such as the "Click to Start" prompt and the sign panel, create a visually unappealing interface.

**Specification
=========**
1. Moves the side panel to the right side of the viewer for improved accessibility.
2. Ensures the first option in the side panel is selected by default, simplifying the document preview process (refer to: https://link.excalidraw.com/l/65VNwvy7c4X/o1Mtd7yyXD).
