feat: Implement Smart Router workflow with User Input and Duplicate Logic (v0.18.0)

Major update to the scanning engine to support "Pause & Resume" workflows.
The system can now halt execution to ask for user input (e.g. Weight) and resume
processing seamlessly.

Key Changes:
- Backend (Global Actions): Added `OPEN_FORM` action type to pause pipeline and request manual input.
- Backend (Routes): Updated `scan_lot` to handle `extra_data` payloads, allowing the pipeline to resume after user input.
- Backend (Logic): Implemented `confirm_duplicate` gatekeeper to handle "Warn vs Block" logic dynamically.
- Frontend (JS): Added `processSmartScan` to handle router signals (Open Modal, Warn Duplicate).
- Frontend (JS): Added `saveSmartScanData` to send original barcode + new form data back to the engine.
- UI: Fixed modal ID/Name conflicts (forcing use of `name` attribute for DB compatibility).
- UI: Restored missing "Cancel" button to Details Modal.
- Config: Added "User Input" rule type to the Rule Editor.

Ver: 0.18.0
