Closes #1165

Summary

This PR fixes an issue where the NLP time parser incorrectly maps midnight to 23:59.

Midnight represents the start of a day (00:00), but the current implementation interprets it as one minute before the next day (23:59).

Changes Made

• Updated midnight parsing in server.js
• Updated midnight parsing in js/utils/nlpDateExtractor.js
• Changed:

{ hours: 23, minutes: 59 }

to:

{ hours: 0, minutes: 0 }

Testing

• Verified parser behavior for midnight
• Verified changes in both server-side and client-side parser implementations
• Verified no unrelated files were modified
• Existing tests pass
