feat: integrate global keyboard shortcuts across multiple components

- Added `KeyboardShortcutsProvider` to `RootLayout` for centralized keyboard shortcut management.
- Implemented `useGlobalKeyboardShortcuts` in `DailyPageClient`, `KanbanPageClient`, and `HomePageClient` to enhance navigation and task management with keyboard shortcuts.
- Updated `KeyboardShortcuts` component to render a modal for displaying available shortcuts, improving user accessibility.
- Enhanced `Header` component with buttons to open the keyboard shortcuts modal, streamlining user interaction.
