[17.0][ADD] search_today_filter

[bizzappdev]

This module enhances the user experience in Odoo by introducing two dynamic filters, Created Today and Updated Today, to the search views of models that include create_date and/or write_date fields. These filters enable users to filter records created or modified on the current date quickly.

Configuration:
- No configuration is required from the Odoo user interface.
- Once installed, the functionality is automatically activated across applicable models.

Usage:

- Open any list view for a model that includes create_date or write_date (e.g., Sales Orders, Contacts, Tasks, Invoices).
- In the search bar, you'll find:
    - Updated Today – filters records with write_date set to today.
    - Created Today – filters records with create_date set to today.
- Click on a filter to apply it.

For models lacking a create_date field, override the class attribute self._search_today_create_fields to use an alternative datetime field in your bridged module.
For example, in queue.job, this can be set as:

```
    _search_today_create_fields = 'date_created'

```
