Strengthen Autoscaler Implementation + UI Cleanup

[iAlexeze]

This PR delivers a set of improvements to the autoscaler runtime and the OperatorBox UI, with a focus on correctness, clarity, and observability.

Summary of Changes

• Strengthened autoscaler evaluation logic
• Improved resolver context by adding .health.*
• Cleaned up UI panels to reflect new health and metrics fields
• Verified autoscale behavior across all advanced examples
• Ensured cross‑binary autoscaling works reliably with cached HTTP sources

Examples Tested

All examples under:

pack: advanced
section: 12-autoscale

Confirmed working:

• 01-without-autoscaler
• 02-based-on-own-metrics
• 03-sibling-in-binary
• 04-sibling-in-cluster

Pending next PR:

• 05-external-friend (cross‑cluster autoscaling)

Resolver Enhancements

Added .health context to the resolver, enabling:

• status.fields to surface live runtime health
• autoscale conditions to reference health
• cross‑CRD health propagation

This lays the foundation for richer orchestration patterns and prepares the system for Orkestra Native Cross‑Operator Protocol (ONCOP).

Why This PR Stops Here

This PR intentionally includes only the completed, stable work.
The next phase — ONCOP (source.host, source.type, URL inference, etc.) — will be implemented in a separate PR to keep review scope clean.
