Fix npm security vulnerabilities with breaking changes

[aranke]

Summary

• Update Angular to 1.8.3 for improved security
• Update prismjs to 1.30.0 to fix DOM Clobbering vulnerability
• Add braces 3.0.3 to fix Uncontrolled resource consumption vulnerability
• Add body-parser 1.20.3 and other secure dependencies
• Add other dependencies explicitly with secure versions (nth-check, marked, etc.)

Test plan

• Package installs correctly with npm install --legacy-peer-deps
• Application builds properly with webpack
• Confirmed that the most critical vulnerabilities are addressed

Note: Some vulnerabilities remain as fixing them would require major breaking changes to the application, particularly around Bootstrap v3, Angular, and webpack ecosystem.
