Changes in basic features

Added support for additional trend and smoothing lines on dashboard charts. This allows you to temporarily change the visualization without saving the changes in the original chart.

Currently:
- Available only for linear charts (Wizard, QL charts, or Editor charts).
- Available only from dashboards.
- Not available for linear charts with the X axis in discrete mode.
- The settings are not retained.
- Not available on public and embedded dashboards for now.
In chart color settings, you can now set a color with a HEX code, use an eyedropper tool, and adjust color transparency.

In DataLens Gallery, enabled viewing a list of all categories and improved category name display in category cards.
Added a sidebar indicator showing the trial period countdown.
Fixed an error that occurred when importing workbooks from files with specific Cyrillic characters in the name.
Improved navigation: the last breadcrumb item is now a link to the current page without parameters.
Added an option to copy a revision ID in the object revision history (for connections, datasets, charts, dashboards, and reports). To do this, in the list of versions, click → Copy ID.
Updated the Neuroanalyst chat UI.
Fixed an error that occurred when creating a dataset from the sidebar navigation.
In reports, fixed the behavior of links to headers during report preview in Presentation mode.

Fixed an issue where filtering of charts by other charts failed to affect global selectors on other dashboard tabs.
Improved the selector setup interface by optimizing the size and layout of UI elements.

In charts, you can now configure X and Y axes without specifying a section field.
Revised the save confirmation behavior when exporting charts:
- For background export, the confirmation window appears after configuring export settings.

Added support for disabling export at the connection level for Editor charts.

Added support for the X-Org-ID and X-Cloud-Org-ID headers when creating new API Connector connections.
When connecting to ClickHouse®, the NULL value under ELSE in the CASE section is no longer replaced by the default type value.
Fixed incorrect behavior of unsaved changes warnings when creating a connection to YDB.
