Complete DRY/KISS architecture refactoring: eliminate SQL duplication and standardize patterns

- SQL Layer Separation: Remove all SQL queries from service layers, achieving perfect Handler→Service→SQL architecture
- Response Standardization: Replace manual ApiResponse construction with helper functions (success_response, success_with_message, success_message_only)
- Sanitization Centralization: Create SanitizeDescription trait to eliminate HTML sanitization duplication across services
- Code Reduction: Delete 1,340 lines of duplicated code while adding 405 lines of clean infrastructure
- Zero Breaking Changes: All API contracts preserved, only internal architecture improved
- Enhanced Security: Automatic response sanitization via SanitizeOutput trait

Created SQL modules:
- src/sql/config.rs: Church configuration operations
- src/sql/media.rs: Media scanning and metadata operations

Refactored services:
- EventsV1Service: Use sql::events module, centralized sanitization
- PendingEventsService: Use sql::events module, centralized sanitization
- ConfigService: Use sql::config module
- MediaScannerService: Use sql::media module
- HymnalService: Simplified complex search query from 200+ to 20 lines

Standardized handlers:
- All handlers now use response helper functions
- Consistent error handling patterns
- Preserved exact JSON response format for frontend compatibility

Result: Perfect DRY/KISS compliance with zero API surface changes

-COMPARISON SUMMARY:
-
-BEFORE:
-- 150+ lines of repeated pagination logic
-- Manual response construction in every handler
-- Duplicate processing logic in 3+ places  
-- Manual error handling in every function
-- Hard to maintain and extend
-
-AFTER:
-- 50 lines using shared utilities
-- Automatic response construction via generic handlers
-- Single shared processing function
-- Centralized error handling
-- Easy to maintain and extend
-
-BENEFITS:
-✅ 70% reduction in code duplication
-✅ Consistent error handling and response formats
-✅ Easier to add new features (pagination, filtering, etc.)
-✅ Better performance through optimized shared functions
-✅ Type-safe operations with compile-time validation
-✅ Centralized business logic for easier testing
-
-KEY PATTERNS ELIMINATED:
-❌ Manual pagination calculations  
-❌ Repeated Json(ApiResponse{...}) wrapping
-❌ Duplicate database error handling
-❌ Copy-pasted processing logic
-❌ Manual parameter validation

-COMPARISON:
-
-BEFORE (DRY violations):
-- Manual pagination logic repeated in every handler
-- Manual ApiResponse construction in every handler  
-- Duplicate database error handling in every handler
-- Separate V1/V2 handlers with 90% duplicated logic
-- Manual multipart processing in every submit handler
-- Manual image processing in every upload handler
-
-AFTER (DRY principles applied):
-- Shared pagination logic via PaginationHelper
-- Shared response construction via handle_* functions
-- Shared database operations via EventOperations
-- Shared conversion logic via converters module
-- Shared multipart processing via multipart_helpers
-- Shared image processing via images utilities
-
-BENEFITS:
-- ~70% reduction in code duplication
-- Consistent error handling across all endpoints
-- Easier to maintain and modify business logic
-- Type-safe operations with better error messages
-- Centralized validation and sanitization
-- Better performance due to optimized shared functions
