feat: integrate tags into HomePage and TasksContext

- Added `initialTags` prop to `HomePageClient` for passing tag data.
- Updated `TasksProvider` to accept and utilize `initialTags`, enhancing tag management.
- Modified `useTags` hook to initialize state with provided tags and conditionally refresh tags based on initial data.
- Updated server-side data fetching in `HomePage` to include tags from the `tagsService`.
