What does this PR do?

Part of VEL-8567: replace the build-time behavior of ember-cli-ifa with the owned OSS Components adapter ahead of the Vite migration. The shared asset-map service/helper keeps the existing runtime names; consumers explicitly opt into manifest injection through injectAssetMap (upfluence/oss-components#716).

In this repo:

• Wraps 1 app/dummy/test build(s) with injectAssetMap, passing through fingerprint settings and rootURL, and writes assets/upfluence-asset-map.json.
• Adds the matching upfluence:asset-map meta placeholder to 2 application/test HTML entry point(s).
• Pins OSS Components to pn/asset-map-service-adapter (lockfile revision 9dcd77cf) and allows its Git-package build through pnpm onlyBuiltDependencies.
• Adds the shared Font Awesome stylesheet (https://uweb.s3.us-east-1.amazonaws.com/fa-current/css/all.min.css) to the app/dummy page(s), ahead of the app stylesheet. It duplicates the Font Awesome that OSS Components still injects, and is groundwork for removing that injection.

Before merging: release OSS Components, replace the Git pin with its published version, and refresh the lockfile. The last two commits carry a [skip ci] marker (an empty one and the Font Awesome one). Strip the markers from the squash-merge message (or omit those commits when merging); otherwise post-merge deploy/release workflows can also be skipped. Run CI on the final release-pin update before merging.
