Add --no-install-recommends to the APT command.
The repository enables hadolint, and this command omits its recommended-package guard. Add the flag to avoid installing unnecessary packages.

Eight eMudhra (emSign) intermediate CAs had recoverable private keys and were revoked on 2026-10-18. Python does not check revocation, so the image's system store (ca-certificates 20250419) still trusts certificates minted through them and connects to https://dv-g3b-emudhra.we-have-a-problem.com/. The fetcher uses requests, which goes through certifi; the requirements are unpinned, so a fresh build already gets certifi 2026.10.19. The system store is what the rest of the image (curl, wget) uses.
The fix lists ca-certificates in the existing apt step, which upgrades it to 20250419+deb13u1, the Debian update that distrusts them. Version 1.1.1 so it ships as a release.
