Fix code-quality CI: resolve npm peer conflict from TypeScript 7 bump

[Copilot]

npm ci in src/java/ws/rest-client fails in the code-quality (22.x) job. The TypeScript 7.0.2 bump conflicts with the peer range typescript >=6.0 <6.1 that the Angular build tooling declares.

This PR does not move TypeScript up. It pins typescript to ~6.0.3 and updates the surrounding dependencies. TypeScript 7 cannot be adopted with current releases, so this is a stopgap until upstream support lands.

• Why 7.x isn't viable yet

  • @angular/compiler-cli, @angular/build and @angular-devkit/build-angular (latest 22.2.1, and 22.3.0-next.0) all declare typescript >=6.0 <6.1. typescript-eslint caps at <6.1.
  • An npm overrides entry for typescript lets npm install succeed, but both tools then fail at runtime:
    • ng build: Cannot read properties of undefined (reading 'Error')
    • ng lint: Cannot read properties of undefined (reading 'Intrinsic')
  • TypeScript 7 is the native compiler and no longer provides the JavaScript API these tools call.
  • Aliasing @typescript/typescript6 for the tooling via overrides doesn't work either. npm requires the root package to satisfy each peer dependency.

• package.json and package-lock.json

  • typescript: ~7.0.2 → ~6.0.3
  • @angular/* and @angular-devkit/build-angular: aligned to ^22.2.1. This also fixes a @angular/common 22.1.1 vs @angular/core peer mismatch.
  • angular-eslint: 22.1.0 → ^22.5.0
  • typescript-eslint: 8.65.0 → ^8.71.0

Follow-up: move to TypeScript 7 once Angular and typescript-eslint publish versions that support it.
