Is your feature request related to a problem? Please describe.
Ollama allows updating of an existing tagged model (use an existing tag on a new model). This info is not visible in the WebUI right now.

E.g. previously gemma2:9b-instruct-q6_K had an ID of 37e9e747b764, but after the recent update, the same tag has become 3827bab50424.

Describe the solution you'd like
It would be great to be able to see if a model is updatable (a local model is updatable if the local hash differs from the remote hash).

Describe alternatives you've considered
It is hard to implement this feature directly in the current UI because ollama models are only listed in dropdowns right now. Perhaps it would be better to create a dedicated "models page" that displays a table of local models, and then implement this feature.
