fix: add condition to skip processing files with a fileIdentifier metadata

- Added `useUpdateSearchParams` hook to manage URL search parameters dynamically.
- Updated `Landing`, `NewChat`, and various parameter components to utilize the new hook for better state management.
- Enhanced styling for dark mode support in chat components.
- Refactored click handlers in `NewChat` to create chat search parameters for navigation.
- Improved accessibility and usability in `DynamicCombobox`, `DynamicInput`, `DynamicSlider`, `DynamicSwitch`, and `DynamicTags` components.
- Introduced `createChatSearchParams` utility to streamline query parameter creation for chat sessions.
