feat(server): implement KV store API and fingerprinting functionality

- Added a new KV store API with endpoints for querying namespaces and key-value pairs.
- Introduced fingerprinting functionality to hash and manage data fingerprints, allowing for efficient change detection.
- Enhanced existing scripts to utilize the new fingerprinting capabilities, enabling conditional execution based on data changes.
- Updated the web interface to include a dedicated KV page for managing key-value entries and displaying their details.
- Improved overall user experience with pagination and search capabilities in the KV management interface.
