fix: Fix indicator parameter configuration and Docker build issues

- Fix indicator parameter values being reset after modification in indicator-analysis page
- Fix Docker build nginx image pull failure (use specific version tag)
- Add Docker build scripts (PowerShell and Bash versions)
- Revert call_indicator feature (temporarily removed to avoid affecting existing indicator execution)
