Pull request overview

This PR attempts to address a high-severity XSS vulnerability (SNYK-JS-ANGULARCOMPILER-14157154) by upgrading @angular/compiler from version 15.2.10 to 19.2.17. However, the upgrade introduces a critical version incompatibility issue that will prevent the application from building or running correctly.

Key Issue:

• Only @angular/compiler is upgraded to v19, while all other Angular packages remain at v15, creating a major version mismatch that will cause build failures

Upgrading only @angular/compiler to version 19.2.17 while keeping all other Angular packages at version 15.1.0 will create severe version incompatibilities. Angular requires all core packages (@angular/animations, @angular/common, @angular/core, @angular/forms, @angular/platform-browser, @angular/platform-browser-dynamic, @angular/router) to be at the same major version.

This mismatch will likely cause:

• Build failures due to incompatible APIs between Angular 15 and 19
• Runtime errors and unexpected behavior
• Issues with @angular/compiler-cli (still at 15.1.0 in devDependencies) being unable to work with the 19.2.17 compiler

To properly fix the security vulnerability, you should either:

1. Upgrade all Angular packages to version 19.2.17 (recommended if compatible with your codebase)
2. Find a patched version of Angular 15 that addresses the XSS vulnerability (e.g., 15.2.11 or later if available)
