interpolate credentialsId in the token viewer

[anusree-bruno]

This PR fixes issue #4744 where the OAuth2 token viewer incorrectly reported "No token found" when variables were used as the Token ID in OAuth 2.0 Client Credentials configuration.

Cause

The credentialsId parameter was not being interpolated with collection variables before being used to find the stored credentials. This caused a mismatch between the interpolated URL and the non-interpolated credentials ID when searching for stored OAuth2 credentials.

Changes Made

Added interpolation for credentialsId: Now properly interpolates variables in the Token ID field
Files Modified:

• packages/bruno-app/src/components/RequestPane/Auth/OAuth2/Oauth2TokenViewer/index.js
• packages/bruno-app/src/components/RequestPane/Auth/OAuth2/Oauth2ActionButtons/index.js

Testing

This fix resolves the scenario where:

1. User configures OAuth 2.0 Client Credentials with a variable as Token ID (e.g., {{my_credentials_id}})
2. User clicks "Get Access Token" - token is successfully retrieved
3. UI now correctly displays the token details instead of showing "No token found"
