This pull request introduces responsive improvements to the navigation tabs in the account banner and account overview banner components, ensuring a better user experience on smaller screens. It also refactors and cleans up related code, and applies various CSS enhancements for improved layout and usability.

Responsive navigation and UI improvements:

• Added logic to both AccountBannerComponent and AccountOverviewBannerComponent to dynamically hide or show tab text based on available width, using @ViewChild, HostListener, and new hideTabText/hideAllText state variables. This ensures tabs remain usable on smaller screens. [1] [2] [3] [4] [5]
• Updated the HTML of both banners to wrap tab text in a span.nav-text and conditionally apply CSS classes for hiding/showing text, improving responsiveness and accessibility. [1] [2]

CSS and layout enhancements:

• Improved tab and button styling, including ellipsis handling for overflowing text, white-space: nowrap for buttons and backup info, and making the navbar horizontally scrollable if needed. [1] [2] [3]
• Enhanced z-index management and overflow handling for sticky banners and dropdown menus to ensure UI elements display correctly. [1] [2] [3]

Code cleanup and refactoring:

• Removed legacy and now-unnecessary logic from AccountOverviewBannerComponent, including date range selection, emissions/source toggles, and related subscriptions, in favor of a new app-account-overview-options component. [1] [2] [3] [4] [5]
• Updated imports in both components to support the new logic and removed unused dependencies. [1] [2]

These changes collectively improve the adaptability, maintainability, and user experience of the account navigation components.
