Rebranding to Scalytics Copilot and Critical Bug Fixes

This PR handles the official rebranding of the project from "Scalytics Connect" to Scalytics Copilot and addresses several critical bugs discovered during the transition, including a broken migration runner.

Key Changes

1. Rebranding & Renaming

Updated all occurrences of "Scalytics Connect" to Scalytics Copilot across:
Backend configuration (package.json, swagger.js, etc.)
Frontend (manifest.json, index.html, and UI components)
Documentation (renamed several .md files in docs/ and updated content)
Environment setup scripts (setup-frontend.sh, start-app.sh)

2. Bug Fixes

Migration Runner Fix:
Resolved an issue in src/config/database.js where database migrations using the runMigration() entry point were being skipped. The runner now correctly supports both up() and runMigration() patterns.
This ensures the columns like isLoading in the messages table are properly created on fresh installs.

Inference Router Safety:
Added a null-check and default assignment for the parameters object in src/services/inferenceRouter.js to prevent TypeError when max_tokens deletion is attempted on an undefined object.

3. New Test Coverage

Inference Router Tests: Added test/inference-router.test.js to verify:

• Correct routing to local vLLM.
• Automatic fixing of non-alternating message sequences (critical for Gemma/Llama models).
• Migration Integrity: Added test/migration-integrity.test.js to ensure all files in src/config/migrations export a valid entry point, preventing future "skipped migration" bugs.

Frontend Smoke Test:
Added frontend/src/App.test.js to verify the application renders without crashing.
