Show deployed version on the web viewer (#257)

Reads PlanViewer.Web assembly version at runtime and renders it in two
places so Joe (and anyone else giving feedback) can tell at a glance what
version is deployed:
- Landing page: small badge appended to the "Powered by Performance Studio"
  line
- Toolbar (when a plan is loaded): badge on the right side next to the
  SQL Server build info

deploy-web.yml now auto-syncs src/PlanViewer.Web/PlanViewer.Web.csproj
Version with src/PlanViewer.App/PlanViewer.App.csproj Version before
publishing, so the displayed version always matches the App release tag
without needing manual csproj bumps in two places. Also widened the
deploy-web path trigger to include App.csproj so version-only releases
still redeploy the web.

Version bump 1.7.2 -> 1.7.3.
