Subject: [PATCH 1/2] fix: add element-call multi-stage build to Dockerfile

upstream/dev added the element-call submodule as a file: dependency
(@element-hq/element-call-embedded) but the Dockerfile had no step to
build it, causing the vite static-copy plugin to fail with:

  No file was found to copy on node_modules/@element-hq/element-call-embedded/dist/*

Add a new element-call-builder stage that:
- Fetches the pinned submodule commit with --depth=1
- Enables corepack to activate yarn 4.x (required by packageManager field)
- Runs yarn build:embedded to produce embedded/web/dist/

The builder stage then COPYs the pre-built package into place before
npm ci, so npm can resolve the file: dep and vite finds the assets.
