fix: [#818] Cursor cannot scan json column

[hwbrzzl]

📑 Description

Closes goravel/goravel#818

This pull request significantly enhances the database row scanning and decoding capabilities, especially for handling JSON data and custom types. It introduces new decode hooks for slices, maps, and types implementing the Scan method, and updates the test suite to validate these improvements. Additionally, it simplifies the codebase by delegating scanning logic and updates dependencies.

Enhancements to Row Scanning and Decoding:

• Added new decode hooks in database/db/row.go to support automatic conversion of JSON strings to Go slices and maps, and to handle types implementing the Scan(any) error interface (such as custom and Carbon types). This improves flexibility and correctness when scanning database rows into Go structs. [1] [2]
• Improved field name matching logic in the decoder to support both snake_case and StudlyCase mappings, increasing compatibility with various struct field naming conventions.

Refactoring and Codebase Simplification:

• Refactored database/gorm/row.go to delegate the Scan method to the new, centralized logic in database/db/row.go, removing duplicated code and reducing maintenance overhead. [1] [2]

Testing Improvements:

• Added comprehensive tests in tests/query_test.go for scanning JSON columns into map[string]any, slices ([]string, []int), and custom structs, ensuring robust support for a variety of data types and structures.
• Updated the test query builder to only enable SQLite tests, likely for focused or faster testing.

Dependency Updates:

• Upgraded the github.com/goravel/framework dependency from v1.15.9 to v1.16.5 and added a new indirect dependency on github.com/urfave/cli/v3 in the test module. [1] [2]

This pull request enhances the database row scanning functionality to properly handle JSON columns and custom types. It introduces new decode hooks for automatic JSON-to-Go conversions and consolidates scanning logic in a centralized location, while adding comprehensive test coverage for the new capabilities.

Key Changes:

• Added three new decode hooks (ToScannerHookFunc, ToSliceHookFunc, ToMapHookFunc) to handle JSON string conversions to slices, maps, and types with custom Scan methods
• Improved field name matching to support snake_case database columns mapping to Go struct fields
• Refactored database/gorm/row.go to delegate to centralized scanning logic in database/db/row.go
