fix: update sidebar icons and enhance DiscoverPage layout

- Updated DiscoverPage to include full height and width styling for better layout.
- Modified sidebar icon visibility logic in migration to ensure 'discover' is added correctly while filtering out specific icons.
- Changed default sidebar icons to replace 'store' with 'discover' for consistency.
