zmNinjaNG

Added a way to view objdetect, alarm, and snapshot frames for an event, like the older zmNinja. Added an on-device assistant backend on iOS and Android, so the assistant can run models locally without a server. Assistant backend choices are now named by who supplies the model, so it is clearer what you are picking. The assistant now understands phrases like "3 days ago" instead of falling back to today. The assistant no longer fails with an error when a local model lacks tool support; it now works with those models over Ollama. Fixed the event server connection dropping after the app was in the background and reopened. Connection failures now name the server that could not be reached instead of showing raw error text. Passwords and tokens are now stripped from logs, including ones sent back by ZoneMinder.
