Replaced DevExpress DxButton components with standard HTML
<button> elements in EnvelopeSenderEditorPage.razor for
"Add Receiver" and "Add Signature" actions. The new buttons
include SVG icons and text for improved customization and
styling.
Updated envelope-viewer.css to add new styles for the
buttons, including `.sender-toolbar-action-btn` and
`.sender-toolbar-action-btn--compact` classes. Removed
unused styles related to DxButton components and adjusted
`.sender-receiver-chip__action` for proper width handling.
These changes improve design flexibility and maintainability.
