Refactor tag handling and add chip localStorage support

Refactored tag handling logic by introducing helper functions to improve clarity and maintainability. Added localStorage support for storing and retrieving chip values associated with entries, ensuring smoother transitions and proper state management across sessions. Simplified backend interactions for the "s" tag and improved display logic for tags with chips.
