Refactor AllTasks Component for Enhanced Filtering and Layout

[stewartshea]

• Redesigned the AllTasks component layout to improve user experience, introducing a sidebar for support tag filtering and a more structured content area.
• Implemented a search input for filtering support tags, enhancing usability when managing tags.
• Updated the display of selected support tags and collections, allowing for easier management and clearer visibility of active filters.
• Improved the presentation of filtered tags with hover effects and selection indicators, making it more intuitive for users to add or remove tags.
• Enhanced error handling and loading states to provide better feedback during data fetching processes.

Note

Low Risk
UI-only refactor that rearranges the AllTasks layout and presentation rendering; low risk aside from potential regressions in filter visibility/scrolling and conditional loading/error display.

Overview
Refactors AllTasks to use a single shared sidebar + content layout for both grouped and presentation modes, replacing the prior special-case full-width presentation view.

The sidebar now consistently hosts support-tag selection (with search + selected chips), collection filtering, and a unified Clear Filters action, while presentation mode’s task list rendering is updated to show loading/error states within the content pane and display up to 3 clickable support-tag chips per task.
