Kaushik Rajan 8ae023574e fix: add build-arg support for proxies and mirrors in Docker builds (#1346)
* fix: add build-arg support for proxies and mirrors in Docker builds (#1260)

Pin Debian images to bookworm, make UV source image configurable,
and pass APT_MIRROR/NPM_REGISTRY/UV_IMAGE through docker-compose.

* fix: ensure build args use consistent defaults across compose and Dockerfiles

UV_IMAGE: ${UV_IMAGE:-} resolved to empty when unset, overriding the
Dockerfile ARG default and breaking `FROM ${UV_IMAGE}`. Also configure
COREPACK_NPM_REGISTRY before pnpm download and propagate NPM_REGISTRY
into the prod stage.

* fix: dearmor NodeSource GPG key to resolve signing error

Pipe the downloaded key through gpg --dearmor so apt can verify
the repository signature (fixes NO_PUBKEY 2F59B5F99B1BE0B4).
