refactor: address issue with bazel resolution of peer dependencies

Key changes include:

- **Removal of PNPM Hook:** The `.pnpmfile.cjs` file, which previously converted peer dependencies into
  direct dependencies, has been deleted. This workaround is no longer necessary with the adoption of dynamic
  imports. The `MODULE.bazel` file has been updated to remove references to it.

- **Dynamic Imports**
  - In the `build_webpack` package, static `import` statements for `webpack` and `webpack-dev-server` are
    replaced with dynamic `import()` calls. This defers their loading until they are actively required during
    the process.
  - In the `ssr-dev-server`, `browser-sync` is now loaded using `createRequire` relative to the workspace
    root, improving resolution reliability.

- **Build Configuration:** Associated `BUILD.bazel` files have been updated to remove dependency declarations that are now obsolete due to the new lazy-loading approach.
