/**
 * NavigationButtonsManager - Manages navigation button UI and state
 *
 * RESPONSIBILITY:
 * ===============
 * This manager owns all logic related to the <swp-nav-group> UI element.
 * It follows the principle that each functional UI element has its own manager.
 *
 * RESPONSIBILITIES:
 * - Handles button clicks on swp-nav-button elements
 * - Validates navigation actions (prev, next, today)
 * - Emits NAV_BUTTON_CLICKED events
 * - Manages button UI listeners
 *
 * EVENT FLOW:
 * ===========
 * User clicks button → validateAction() → emit event → NavigationManager handles navigation
 *
 * SUBSCRIBERS:
 * ============
 * - NavigationManager: Performs actual navigation logic (animations, grid updates, week calculations)
