merge: reconcile Erik-deployed fixes with Gitea feature branch (origin/main)
Merges 28 Gitea commits (Transceiver Academy, dashboard features A-P, equivalence
matchers OPN/spec, Abverkauf velocity engine, Flexoptix detail sync, SQL 111-118,
MCP equivalences tool, training data) with 22 Erik-local commits (price chart,
fmtSpd, supply-squeeze per-SKU fix, research-robot actions, NADDOD warehouse,
FS competitor stock, reorder bloat fix, flexoptix empty-token fix, vendor
reliability, blog WireGuard failover).
Only 2 files changed on both sides; ort auto-merged both cleanly. Manually
resolved a resulting duplicate GET /api/hype-cycle/market-signals: kept the
Erik handler (technologies+marketSignalScore+drivers+globalContext, matches the
merged dashboard), removed the Gitea Multi-source variant (preserved in history).
All 3 packages build with 0 TS errors. Safety: branch erik-pre-reconcile-20260607,
bundle _RECON_full-backup-20260607.bundle (also on Fearghas), bulk-price WIP in
stash@{0}, untracked SQL backed up to _RECON_untracked_sql_20260607/.
