Speaker identification and summary improvements

Improvements

• Speaker suggestions map to the correct person.. Fixed an issue where a suggested speaker could be linked to the wrong participant, so names now line up accurately with each voice.
• More accurate speaker matching.. Speaker matching is more reliable, pairing the right advisor and client with each voice.
• Live status during summary generation.. Recordings now show a loading state while speaker analysis and the meeting summary are generated, then reveal the results when they complete.
• Sharper meeting summaries.. Reworked summary generation so events are attributed to the correct person and advisors and clients are clearly distinguished.
• Clearer speaker assignment.. The speaker-assignment view is easier to read, with candidate participants shown beside their avatars and clearer labels throughout.
• More focused participant details.. Participant details are more concise, adding to the meeting summary instead of repeating it.
