Fix application startup bugs and database query inconsistencies

[Copilot]

Application had multiple blocking issues: duplicate code in user module, incorrect database queries referencing non-existent columns, legacy Flask code mixed with FastAPI, and OpenAI client initialization failing at import time.

Changes

Database Query Fixes

• vox/user.py, vox/chat.py, vox/recordings.py, vox/socketio_handlers.py: Fixed queries that incorrectly referenced session_id on users table. Schema uses sessions table to link sessions to users:

# Before (broken)
user = await conn.fetchrow("SELECT * FROM users WHERE session_id = $1", sid)

# After (correct)
session_row = await conn.fetchrow("SELECT user_id FROM sessions WHERE session_id = $1", sid)
user = await conn.fetchrow("SELECT * FROM users WHERE user_id = $1", session_row["user_id"])

Code Cleanup

• vox/user.py: Removed duplicate module content (entire file was duplicated with slight variations)
• vox/socket_handlers.py: Deleted legacy Flask-style socket handler that was incompatible with FastAPI

OpenAI Client Fix

• vox/llm.py: Changed from module-level client initialization to lazy factory pattern to prevent import failures when API key is unset

Graceful Startup

• vox/fastapi_app.py: App now starts without database connection for local development

Frontend Fixes

• static/scripts.js: Fixed undefined pitch/hnr variables in socket handler, fixed references to non-existent DOM elements, added missing sendChat() function

Dependencies

• requirements.txt: Added missing itsdangerous, bcrypt
• init_db.py: Fixed schema path from 0.1.7/docs/ to docs/

Original prompt

I want you to make this functional and create issues if needed for additional bugs and problems we might occur.

@copilot Is this fully OpenRouter compatible?

Yes, the code is fully OpenRouter compatible. The vox/llm.py module uses the OpenAI Python client configured for OpenRouter:

• Base URL: OPENROUTER_API_BASE env var (defaults to https://openrouter.ai/api/v1)
• API Key: OPENROUTER_API_KEY env var
• Model: google/gemini-2.0-flash-001 (OpenRouter model format)

All LLM calls (chat_with_llm(), generate_feedback()) go through this centralized module. Just set your OPENROUTER_API_KEY in your .env file and it will work.
