Proposal/Annotator Mode Upload Model Run: Either removing the upload button or supporting the upload button with a default that the uploaded model is a 'proposal'.

Background:

The annotator mode used to be called 'proposal' so you'll see that referenced a lot in the code.
https://github.com/ResonantGeoData/RD-WATCH/blob/main/vue/src/router.ts#L16
The above router will take you into proposal mode.
https://github.com/ResonantGeoData/RD-WATCH/blob/main/vue/src/components/LayerSelection.vue#L11C1-L12C1
That code can determine if you are in the proposal/annotator mode by looking at the route to determine it.

Option 1 - Disabling Upload Model:
You could make the visibility of upload model run only occur when not in proposal mode and not in scoring mode here: https://github.com/ResonantGeoData/RD-WATCH/blob/main/vue/src/components/ModelRunList.vue#L192

Option 2 - supporting proposal uploads:
If you want to support proposal uploading, which may be handy in the future. You would keep this in there for proposal mode and then edit the logic in the upload-model-run component to add an additional 'proposal' flag when loading the data.

As seen in the upload script:
https://github.com/ResonantGeoData/RD-WATCH/blob/main/scripts/loadModelRun.py#L120
The proposal is a boolean option when posting to the endpoint.

https://github.com/ResonantGeoData/RD-WATCH/blob/main/rdwatch/core/models/model_run.py#L46
The ModelRun model has a proposal option during creation where this can be added during your processing of the upload: https://github.com/ResonantGeoData/RD-WATCH/blob/main/rdwatch/core/tasks/__init__.py#L859
So just masking it so that upload-model-run vue component understands that it is currently being used in the proposal route and the upload should be processed as a proposal could work, or just disabling the button for now from the proposal route.

Updated to hide the upload button in the annotator view.
