ami-build.sh: hardcoded DOCKERLABEL pins AMI to a stale OpenEMR version

[kojiromike]

packages/standard/ami/ami-build.sh hardcodes the default Docker tag near the top:

DOCKERLABEL=:7.0.3

Anyone building the AMI without passing -d gets 7.0.3 regardless of what's current on Docker Hub. The value drifts silently every release.

Options worth considering:

• Drop the default and require -d (fail fast rather than ship stale).
• Resolve "latest stable" dynamically at build time from Docker Hub or a pinned manifest in this repo.
• Move the default into a release-tracked variable file (e.g., packages/standard/VERSION) that's updated as part of the release process.

Flagged on PR #649 (review thread on line 6).

What's the most sensible way to programmatically work out the current stable version?

I'm fine with requiring -d and moving on with our life, but I'd feel better if I knew how to answer that.
