chore: set Backstage supportedVersions to overlays target 1.49.4 (redhat-developer#2540)

* chore: set supportedVersions to overlays target 1.49.4

Follow-up to redhat-developer#2538. Use versions.json Backstage target for all Package
metadata so Extensions catalog shows RHDH platform compatibility.
Replaces per-workspace source.json values that understated compatibility
(e.g. 1.49.3, 1.43.1) per review feedback.

* fix(x2a): add appConfigNotRequired for empty appConfigExamples

Satisfy validate-app-config-examples.py for x2a-dcr and x2a-mcp-extras.
