Fix Docker build failure: downgrade Go version from 1.24 to 1.23.4

[cased]

Problem

Cardinal service Docker builds are failing because they reference Go 1.24, which hasn't been released yet. The latest stable Go version is 1.23.x.

Error: Failed to build images: Build failed when Docker attempts to pull non-existent golang:1.24 and golang:1.24-bookworm base images.

Sentry Issue: https://argus-labs.sentry.io/issues/7012482030/

Solution

Downgrade Go version from 1.24 to 1.23.4 across all references:

1. go.mod - Update Go toolchain version
2. cardinal.Dockerfile - Update base image to golang:1.23
3. cardinal.go - Update dependency image to golang:1.23-bookworm

Changes

• ✅ go.mod: go 1.24.0 → go 1.23.4
• ✅ cardinal.Dockerfile: FROM golang:1.24 → FROM golang:1.23
• ✅ cardinal.go: golang:1.24-bookworm → golang:1.23-bookworm (2 occurrences)

Testing

• Verified golang:1.23 and golang:1.23-bookworm images exist on Docker Hub
• All three files updated consistently

Impact

• Priority: Critical - blocks all Cardinal service builds
• Scope: Production issue affecting all users
• Risk: Low - straightforward version downgrade to stable release
