wiki: audit + archive stale pages; refresh Home for 2026-05-11 wave

- Archived 20 pre-refactor pages to wiki/Archive/ with standard banners:
  - All 6 architecture/ pages (old _loadConfig/_setupSpecificClass internals,
    pre-refactor S88 hierarchy, deployment blueprint)
  - All 3 sessions/ logs (Apr-07 + Apr-13 session summaries)
  - findings/open-issues-2026-03.md (issues 1-5 all resolved by refactor)
  - concepts/generalfunctions-api.md (missing BaseDomain/BaseNodeAdapter)
  - concepts/sources-readme.md (empty PDF placeholder, never populated)
  - manuals/nodes/rotatingMachine.md + measurement.md (superseded by per-repo wikis)
  - Top-level SCHEMA.md, index.md, log.md, metrics.md, overview.md,
    knowledge-graph.yaml (all Apr-07 snapshot, pre-refactor)
- Kept wiki/concepts/ domain pages (ASM, PID, pump-affinity, settling, etc.)
- Kept wiki/findings/ proven results (BEP, NCog, curve-non-convexity, stability)
- Kept wiki/manuals/node-red/* (FlowFuse + Node-RED runtime docs, still current)
- Kept wiki/tools/* (utility scripts)
- Updated wiki/Archive.md index with 20 rows
- Fixed wiki/Home.md: Tier 6 was wrongly marked done; corrected to pending;
  Tier 9 updated to reflect 2026-05-11 in-progress wave
