Switch to pydantic

[liudger]

This pull request migrates the codebase from mashumaro and orjson to pydantic v2 for data modeling and validation, and refactors all models and related logic to use pydantic's features. It introduces a new type conversion utility for BSB-LAN values and updates all model classes and instantiations accordingly. The changes also update dependencies and remove now-unnecessary type ignores. The most significant changes are grouped below.

Migration from mashumaro/orjson to pydantic:

• Replaced mashumaro and orjson dependencies with pydantic>=2.0 in pyproject.toml, and updated linting config to reflect the new base class and compatibility notes. [1] [2] [3]
• Refactored all data models in src/bsblan/models.py to use pydantic.BaseModel instead of @dataclass and DataClassJSONMixin, updating field definitions, default values, and type annotations to leverage pydantic's validation and configuration. [1] [2] [3] [4] [5] [6] [7]

Type conversion and validation improvements:

• Introduced _convert_bsblan_value utility and a model_validator in EntityInfo to handle conversion of raw BSB-LAN values to appropriate Python types (e.g., float, int, time) before model validation, ensuring consistent and reliable data handling. [1] [2]
• Updated all usages of .from_dict() to .model_validate() to construct models using pydantic's validation mechanism in src/bsblan/bsblan.py. [1] [2] [3] [4] [5]

Type annotation and documentation updates:

• Updated all model field type annotations to be more specific, e.g., EntityInfo[float], EntityInfo[int], EntityInfo[time], and adjusted docstrings and comments for clarity and accuracy. [1] [2] [3] [4] [5]

Minor code and style cleanups:

• Removed unnecessary type: ignore[assignment] comments as type conversions are now handled by the new validation logic. [1] [2]

These changes modernize the codebase, improve type safety, and set the foundation for better maintainability and extensibility.

Pull request overview

This PR migrates the data modeling layer from mashumaro with orjson to pydantic v2, modernizing the codebase and improving type safety. The migration introduces a new value conversion utility that handles BSB-LAN's string-based JSON responses and refactors all model classes to use pydantic's validation framework.

Changes:

• Replaced mashumaro and orjson dependencies with pydantic>=2.0 and updated all model classes to inherit from BaseModel instead of using @dataclass with DataClassJSONMixin
• Introduced _convert_bsblan_value() utility function and a model_validator in EntityInfo to convert raw BSB-LAN string values to appropriate Python types (float, int, time) before pydantic validation
• Updated all model instantiation calls from .from_dict() to .model_validate() and removed now-unnecessary type: ignore comments
