Application inference profiles show ARN instead of profile name in `/models` API

[Cabeda]

Describe the bug
Application inference profiles are displayed with their full ARN instead of the human-readable inferenceProfileName in the /models API response, making it difficult for users to identify and select profiles in OpenWebUI.

Please complete the following information:

• Which API you used: /models
• Which model you used: Application inference profiles for claude sonnet 4.5 (e.g., arn:aws:bedrock:eu-central-1:954976287784:application-inference-profile/0h48dnxmrxnl)

To Reproduce
Steps to reproduce the behavior:

1. Enable application inference profiles: ENABLE_APPLICATION_INFERENCE_PROFILES=true
2. Create an application inference profile in AWS Bedrock with a friendly name (e.g., "my-team-claude")
3. Call GET /models API
4. Observe that the profile appears with its ARN instead of the profile name

Example response:
json
{
"object": "list",
"data": [
{
"id": "arn:aws:bedrock:eu-central-1:954976287784:application-inference-profile/0h48dnxmrxnl",
"object": "model",
"owned_by": "bedrock"
}
]
}

Expected behavior
The model ID should use the inferenceProfileName instead of the ARN:

json
{
"object": "list",
"data": [
{
"id": "my-team-claude",
"object": "model",
"owned_by": "bedrock"
}
]
}

Root Cause
In src/api/models/bedrock.py line 189, the code uses the ARN as the dictionary key instead of the profile name:

python

Current code (line 189)

for profile_id, metadata in profile_metadata.items():
if metadata.get("underlying_model_id") == model_id:
model_list[profile_id] = {"modalities": input_modalities} # profile_id is the ARN

The inferenceProfileName is retrieved (line 162) but not used as the model ID:
python
profile_metadata[profile_arn] = {
"underlying_model_id": model_id,
"profile_type": "APPLICATION",
"profile_name": profile.get("inferenceProfileName", ""), # Retrieved but not used
}

Additional context
The fix requires:

1. Using inferenceProfileName as the model ID in the response
2. Maintaining ARN mapping internally for Bedrock API calls (since Bedrock requires ARNs, not names)
3. Updating _invoke_bedrock() to resolve profile names back to ARNs when calling Bedrock APIs

This affects user experience in where users see cryptic ARNs instead of meaningful profile names when selecting models.
