Visualize ResourceSet step-based reconciliation

[dgunzy]

Gap

Flux Operator v0.53 introduced step-based reconciliation for ResourceSets (spec.steps — an ordered list of named steps reconciled in sequence, mutually exclusive with resources/resourcesTemplate). Our vendored CRD and generated models already include the field, but nothing in the TUI surfaces it: a multi-step ResourceSet looks identical to a flat one, and there is no way to see which step is in progress or which step failed.

What should happen

• Show step names and per-step progress/state in the ResourceSet detail and/or history views
• Consider representing steps in the graph view, since steps are effectively an ordered dependency chain (step N → step N+1)
• Verify the reconciliation history view distinguishes step-based runs

Sequencing

Independent — nothing blocks it and it blocks nothing. Small scope; good first pick. Complementary to #204 (ResourceSet inventory in the graph); neither blocks the other.

Suggested order: #193 → #192 → #204 → #194 → #195 → #197 → #196 (#198 is ongoing tracking; #191 ✅ shipped in 0.11.0)
