refactor(server): improve URL change detection and context handling

- Renamed `ensureDataObject` to `passContext` and added `mergeData` for better context management.
- Updated `detectUrlChanges` to utilize the new context handling functions, improving data merging and response handling.
- Enhanced evaluation of JSONata expressions with a new `evalCtx` function to streamline context passing.
- Adjusted test assertions to reflect changes in output structure from `data` to `output`.
