feat: Complete Migration 004 Complexity Resolution (Phases 1-4)

- Phase 1: Simplify Migration Definition ✅
  * Remove duplicate SQL definitions from migration 004
  * Eliminate recovery logic that could cause duplicate execution
  * Establish single source of truth for migration SQL

- Phase 2: Fix Database Result Handling ✅
  * Remove DatabaseResult type assumptions from migration code
  * Implement database-agnostic result extraction with extractSingleValue()
  * Normalize results from AbsurdSqlDatabaseService and CapacitorPlatformService

- Phase 3: Ensure Atomic Execution ✅
  * Remove individual statement execution logic
  * Execute migrations as single atomic SQL blocks only
  * Add explicit rollback instructions and failure cause logging
  * Ensure migration tracking is accurate

- Phase 4: Remove Excessive Debugging ✅
  * Move detailed logging to development-only mode
  * Preserve essential error logging for production
  * Optimize startup performance by reducing logging overhead
  * Maintain full debugging capability in development

Migration system now follows single-source, atomic execution principle
with improved performance and comprehensive error handling.
