feat(ui): make React Query DevTools configurable (#642)

* feat(ui): make React Query DevTools configurable

- Add showQueryDevtools setting to app store with persistence
- Add toggle in Global Settings > Developer section
- Move DevTools button from bottom-left to bottom-right (less intrusive)
- Support VITE_HIDE_QUERY_DEVTOOLS env variable to disable
- DevTools only available in development mode

Users can now:
1. Toggle DevTools on/off via Settings > Developer
2. Set VITE_HIDE_QUERY_DEVTOOLS=true to hide permanently
3. DevTools are now positioned at bottom-right to avoid overlapping UI controls

* chore: update package-lock.json

* fix(ui): hide React Query DevTools toggle in production mode

* refactor(ui): remove VITE_HIDE_QUERY_DEVTOOLS env variable

The persisted toggle in Settings > Developer is sufficient for controlling
DevTools visibility. No need for an additional env variable override.

* fix(ui): persist showQueryDevtools setting across page refreshes

- Add showQueryDevtools to GlobalSettings type
- Add showQueryDevtools to hydrateStoreFromSettings function
- Add default value in DEFAULT_GLOBAL_SETTINGS

* fix: restore package-lock.json from base branch

Removes git+ssh:// URL that was accidentally introduced
