Enhance migration templates with critical omission prevention

Add comprehensive guidance to prevent common migration oversights:
- Remove unused notification imports
- Replace hardcoded timeout values with constants
- Remove legacy wrapper functions
- Extract long class attributes to computed properties
- Replace literal strings with constants

Based on lessons learned from ContactQRScanShowView.vue migration.
Includes validation commands and specific examples for each pattern.
