client-api: fix misspelled neighborhood setting keys in G_API_SETTINGS

[lmeyerov]

Summary

client-api has misspelled neighborhood setting keys in G_API_SETTINGS, while adjacent docs/comments and client-api-react use the correctly spelled names.

Evidence

• Misspelled keys in projects/client-api/src/index.js:
  • neighbhorhoodHighlight at line 1199
  • neighbhorhoodHighlightHops at line 1200
• Same file docs/comments use correct spellings:
  • neighborhoodHighlight and neighborhoodHighlightHops around lines 1247-1248
• client-api-react bindings use correct spellings:
  • projects/client-api-react/src/bindings.js lines 15-16

Why this matters

Consumers calling updateSetting() with correctly spelled keys may fail or behave unexpectedly due to cross-surface naming inconsistency.

Requested fix

1. Add correctly spelled keys to G_API_SETTINGS:
   • neighborhoodHighlight
   • neighborhoodHighlightHops
2. Keep misspelled keys as temporary aliases for backward compatibility:
   • neighbhorhoodHighlight
   • neighbhorhoodHighlightHops
3. Emit deprecation warning when misspelled aliases are used.
4. Add tests ensuring both spellings resolve to identical model paths.
5. Update changelog/docs.
