Align Angular compiler with compiler-cli in ndsweb

[Copilot]

PR #107 updates @angular/compiler-cli, but leaves @angular/compiler on an older patch release. That version skew breaks the Nx web build when Angular internals expected by the compiler CLI are no longer present in the runtime compiler package.

• Root cause

  • @angular/compiler-cli was bumped to 21.2.13
  • @angular/compiler remained at 21.2.7
  • Nx/Angular tooling loaded incompatible compiler artifacts and failed during the production build

• Change

  • Bump @angular/compiler to ~21.2.13 in ndsweb/package.json
  • Update the lockfile entry so dependency resolution matches the declared package version

• Why this is sufficient

  • Keeps the Angular compiler pair on the same patch line
  • Avoids broader dependency movement in the web UI toolchain
