Fix JavaScript errors and auto-populate issues

- Fix loadProtocolMappings reference error in dashboard.js by calling loadAllSignals()
- Add debugging to populateModalFields to identify field availability issues
- Ensure protocol mapping tab is activated before auto-populating from discovery
- Add delay to ensure tab content is loaded before attempting auto-population
