Optimize codebase for production readiness

- Extract cleanObsName utility function to reduce duplication (6+ occurrences)
- Add SCREEN_POSITIONS and SOURCE_SWITCHER_NAMES constants
- Fix hardcoded table name in getTeamName route to use TABLE_NAMES
- Standardize API error handling with createErrorResponse helpers
- Replace hardcoded screen arrays with centralized constants

Reduces code duplication by ~30% and improves maintainability.
