Pull request overview

This PR applies linting fixes to address gosec security warnings and formatting issues throughout the codebase.

Changes:

• Added gosec nolint directives with explanatory comments for intentional security suppressions (pprof endpoints, error handling in shutdown)
• Changed maxSize parameter type from int64 to int32 in GetUpdatesForType method across all interfaces, implementations, mocks, and call sites to match AWS DynamoDB SDK requirements
• Applied multi-line formatting to function calls and definitions with many parameters for improved readability
