fix(desktop): render popup overlays in packaged builds

Popup pages loaded their scripts as classic <script src> tags, which the
renderer build never bundles, so an installed app rendered only the static
markup: the recording tip stayed at 0:00 with no wave bars and live captions
showed nothing.

- declare popup scripts as modules so the build emits them, and fail
  packaging when a renderer page references an asset that was never produced
- hold popup IPC until the renderer has loaded and re-assert visibility on
  every show, so a popup hidden once still appears next time
- surface popup renderer console and load failures in the main log

Every pipeline that runs `npm run build --workspace=@d3ro/desktop` (`.forgejo` release/portable, `.github` CI/release) then runs `scripts/ci/verify-desktop-renderer-bundles.mjs`, which fails packaging when a renderer page references an asset the build did not emit (GAP-INFRA-05).
