feat(frontend): Implement notification settings with separate drawers and improved design.

- Add shadcn/ui drawer and switch components
- Create NotificationFiltersDrawer for editing notification filters
- Create DiscordConfigDrawer with test functionality
- Create TelegramConfigDrawer with test functionality
- Add reusable EditButton component for consistent design language
- Refactor Settings page to use separate drawers per configuration type
- Remove test notifications card, integrate testing into service drawers
- Simplify notification service status indicators for cleaner UI
- Remove redundant service descriptions for streamlined layout
