feat: improve database migration comparison and UI display

- Enhanced migration service to filter empty/default records from comparisons
- Updated comparison output to exclude records without meaningful data
- Improved UI display with better visual hierarchy and count indicators
- Added security improvements to prevent sensitive data exposure
- Fixed settings migration to properly handle MASTER_SETTINGS_KEY vs account DIDs
- Updated verification display to show filtered counts and detailed differences
- Improved data formatting for contacts, settings, and accounts sections
- Added proper filtering for missing records to avoid counting empty entries

Changes:
- Filter SQLite records to only include those with actual DIDs/data
- Update comparison counts to reflect meaningful differences only
- Enhance UI with count indicators and better visual organization
- Replace sensitive data display with boolean flags (hasIdentity, hasMnemonic)
- Fix settings migration logic for proper DID field handling
- Improve verification message to show detailed breakdown by type
- Add proper filtering for missing records in all data types

Security: Prevents exposure of mnemonics, private keys, and identity data
UI/UX: Cleaner display with better information hierarchy and counts
Migration: More accurate comparison results and better debugging visibility
