- sft.py GET /config: use `or {}` guard so `sft: ~` (null YAML) doesn't
return None instead of the default empty config
- CorrectionsView: convert handleCorrect/Discard/Flag and handleUndo from
optimistic to pessimistic — queue mutation only happens after server
confirms; failures leave item in queue so user can retry cleanly
- SettingsView: call loadSftConfig() on mount so saved bench_results_dir
is populated instead of always starting empty
- Add /corrections route to Vue router (lazy-loaded CorrectionsView)
- Add Corrections nav item (✍️) to AppSidebar after Benchmark
- Add cf-orch Integration section to SettingsView with bench_results_dir
field, run scanner, and per-run import table
- Add GET /api/sft/config and POST /api/sft/config endpoints to app/sft.py
