fix: Use user profile name instead of hardcoded 'User' for speaker_name

[smian1]

Summary

When is_user: true, the speaker_name was hardcoded to "User" instead of using the user's actual profile name.

Fix

Fetch the user's name from their profile via get_user_profile(uid) and use it for is_user segments. Falls back to "User" if no name is set.

Code Review

This pull request modifies the _add_speaker_names_to_segments and _add_speaker_names_to_payload functions in backend/routers/developer.py, backend/routers/mcp.py, and backend/utils/webhooks.py. The changes involve fetching the user's name from their profile and using it as the speaker_name for user-identified transcript segments, instead of the previously hardcoded 'User' string. If the user's name is not available in their profile, it defaults back to 'User'. There were no review comments provided.

Pull request overview

This PR fixes the hardcoded "User" speaker name in transcript segments by fetching and using the actual user's profile name. When segments are marked as is_user: true, the system now retrieves the user's name from their profile and uses it, falling back to "User" if no name is set.

Key Changes:

• Fetches user profile data via get_user_profile(uid) to retrieve the user's actual name
• Applies the user's name to is_user segments across webhook payloads and API responses
• Implements consistent fallback logic (or 'User') when no profile name is available

• The function _add_speaker_names_to_segments is duplicated between this file and backend/routers/mcp.py with nearly identical implementations. While the PR correctly adds user profile name fetching to both instances, this duplication creates a maintenance burden. Consider extracting this shared logic into a common utility module (e.g., backend/utils/conversations/speaker_names.py) to avoid having to maintain the same code in multiple places.
