fix: resolve line length violations (80+ characters)

- refactor src/cli/Main.py: split long logging config, user prompts, and method calls
- refactor src/config/settings.py: break long Field definitions into multiple lines
- refactor src/core/providers/enhanced_provider.py: split provider lists, headers, and long f-strings
- refactor src/core/providers/streaming/voe.py: format HTTP header setup
- update QualityTODO.md: mark all line length violations as completed

All files now comply with 88-character line limit. Code readability improved with
better-structured multi-line statements and intermediate variables for complex expressions.
