Summary

Fixes #6145. On the Hands "开发团队" (dev team) settings editor, typing values into the input fields and clicking Save left the UI showing the old/empty values instead of what was just saved — the data appeared not to persist.

Root cause

HandSettingsEditor (crates/librefang-api/dashboard/src/pages/HandsPage.tsx) keeps edits in a local draft. On a successful save it clears the draft (setDraft({})), after which each input falls back to settings.current_values[key] — sourced from the useHandSettings query (key handKeys.settings(handId)).

But useUpdateHandSettings only invalidated handKeys.lists() and handKeys.detail(handId):

onSuccess: (_data, variables) => {
  qc.invalidateQueries({ queryKey: handKeys.lists() });
  qc.invalidateQueries({ queryKey: handKeys.detail(variables.handId) });
  // settings query never invalidated → current_values stays stale
},

The backend PUT /api/hands/{id}/settings persists the config (the editor only allows saving while the hand is active, so there is always a live instance to write to), but the cached settings query was never refetched. So once the local draft was cleared, the inputs reverted to the pre-save current_values.

Fix

Invalidate the settings query in onSuccess so the editor refetches and displays the saved values:

 onSuccess: (_data, variables) => {
   qc.invalidateQueries({ queryKey: handKeys.lists() });
   qc.invalidateQueries({ queryKey: handKeys.detail(variables.handId) });
+  qc.invalidateQueries({ queryKey: handKeys.settings(variables.handId) });
 },

Verification

• Extended the existing useUpdateHandSettings test to assert the handKeys.settings(handId) invalidation. Confirmed it fails before the fix and passes after.
• pnpm test --run — 785 passed (80 files)
• pnpm typecheck — clean
• pnpm lint — 0 errors (pre-existing baseline warnings only)
• pnpm build — ok
