chore(crypto): upgrade OpenSSL to 3.x

[NaeemKK]

Remove custom OpenSSL 1.1.1x wiring from build and container setup and use system OpenSSL with a minimum supported version of 3.0.5. Also, update OpenSpec dependency requirement and scenarios to match current behavior.

Pull request overview

This PR updates BartonCore’s build/container setup to stop wiring in a custom OpenSSL 1.1.1 build and instead rely on system OpenSSL with a minimum supported version of 3.0.5, aligning OpenSpec requirements and build-time dependency checks accordingly.

Changes:

• Update OpenSpec dependency requirements and scenarios to reflect OpenSSL 3.0.5+.
• Remove Docker image steps that downloaded/built OpenSSL 1.1.1v (and the related curl build/linking).
• Update CMake dependency version checks to require OpenSSL >= 3.0.5 (dropping the previous 1.1.1 max constraint) and remove Matter build-time PKG_CONFIG_PATH override.

Pull request overview

This PR updates BartonCore’s build, container, and OpenSpec requirements to drop the custom OpenSSL 1.1.1x wiring and rely on system OpenSSL with a minimum supported version of 3.0.5, aligning the documented dependency constraints and build scenarios with the new baseline.

Changes:

• Update dependency policy/specs to require OpenSSL >= 3.0.5 and adjust OpenSSL version-check scenarios accordingly.
• Remove Docker image steps that built/used a custom OpenSSL 1.1.1v (and curl linked against it), reverting to system OpenSSL/curl packages.
• Remove CMake/script environment overrides that hard-coded /usr/local/openssl for RPATH/LD paths and Matter build wiring.

LGTM once the Copilot comment is resolved.

changes to dockerfiles require a rev of the docker/version file (source of truth for docker image version tag).

Once a new docker version is merged to main, we have to push the image to the registry (we should generate CI for this at some point). The Dockerfile has some instructions for this at the top. If, for some reason, you don't have permission to let me know and I can push it.

Requesting a small change to the commit message type: this would be build instead of chore. Docker‑related changes generally fall under build.
