This update introduces a new button within the holiday attest form, streamlining the process for directly allocating paid time off. Previously, users had to navigate through multiple steps to create an allocation; now, they can do it more quickly and efficiently. This improves user experience and reduces administrative overhead.

In this PR, we added a button in the holiday attest in the year n1 to ease the flow of creating an allocation directly.

This update simplifies event slot creation by allowing users to confirm and adjust event time ranges when adding slots outside the original event timeframe. It also enhances the user interface with a new 'Slots' button and a more intuitive form dialog for slot creation, improving overall usability.

Purpose
=======
Improve the event slots feature and some other small improvements.

Specification
===========
Event form:
- Add a "Slots" stat button to ease access to slots in addition
to the link already present next to the multiple slots field.
- Make "Sales Start" hidden by default for the event tickets.
- Make sure the left column fields labels are correctly aligned
with the title. A bottom margin was missing underneath the event image
and was messing the form display.

Slot views:
- In calendar view, instead of restricting the creation of slots outside of the event time range,
ask confirmation and adjust the event time range to include the new slots.
- In list view, removing the editable bottom behavior which is messy and tricky to use from mobile.
Instead opening the slot form in a dialog. This also now provides the timezone info to the user.
- In calendar and list view, adding a "New" button to allow single event slot creation.
- Add an hint for the user to make sure they understand that they need
to select days in order to add multiple slots.
- Changing the multi create "Add" button color to primary to make it more noticeable at first sight.
- For the slots out of time range validation error. Format the event time range the same way
as the slot time range so that it's easier to compare the 2.

This update separates the granularity of time off requests from allocations, allowing accrual plans in hours to be taken in days when needed. This change enhances flexibility in managing employee time off, aligning with how accruals are currently handled. The update also includes related data and test updates.

Previously, the time off given to the employee (Accrued/Allocated) had the same granularity of that which the employee requests, for example the employee accrues hours in his plan and consequently can use this time off type in hours, or can only accrue days to time off types in days and half-days. 
This task separates the dependency between both so that accrual plans in hours can be taken only in days if needed

This update streamlines how Odoo handles binary data (like images and files) by moving away from base64 encoding. This change improves performance and prepares Odoo for future changes in how binary data is stored in the cache, ultimately reducing data usage and simplifying the codebase.

`datas` is base64-encoded and we directly decode it once set. Most of code should use `raw` directly and avoid handling base64 encoded data, because in the future we will change the cache representation to avoid handling encoded values.

This PR simplifies current usages and will allow to change the representation of binary fields in cache (which are today base64 encoded). base64 takes more space and there is a lot of encoding/decoding involved depending on the abstraction layer, the end goal is to only handle raw data and encode only for the client.

- In `odoo.tools.images` a few base64 functions are deprecated (one remaining for later).
- Allow importing files (see convert) without going though base64.
- Binary fields have now `convert_to_read` (encode as base64) and `convert_to_write` (use the cache format) defined. The *read format* is used by the client and should not be used in the models.
- base tests define common data that can be reused.

Administrators can configure a new setting to display important information, such as planned maintenance, directly on the home screen. This provides a centralized way to communicate critical updates to users.

Display a message on home menu based on an ir.config_parameter that can be added directly in the database by the system administrator.

The ir.config_parameter is sysadmin.message and should be a json loadable. The format shoud be something like this:
{
    "type": "warning",
    "replace": false,
    "warning_type": "user",
