* fix: update Docker base images to latest Python 3.12 to resolve CVEs - Update all Dockerfiles from python:3.12.13-slim-trixie to python:3.12-slim-trixie - This ensures automatic security patches for Debian base image CVEs - Affects nightly builds (base, main, main-all) and release builds (backend, ep) - Using unpinned patch version (3.12 vs 3.12.13) follows security best practices * fix: update builder stage to Debian Trixie for consistency - Update all Dockerfiles from bookworm-slim to trixie-slim in builder stage - Ensures consistency between builder and runtime Debian versions - Eliminates CVEs in both build and runtime environments - Uses ghcr.io/astral-sh/uv:python3.12-trixie-slim for all builders
