Add HTML report CLI workflow

[byemaxx]

This pull request introduces a new modular architecture for the metax.report package, adding robust configuration, CLI, registry, and path management systems, as well as new HTML templates for figure and plot rendering. The main themes are improved configurability, extensibility, and user interface enhancements for report generation.

Core Infrastructure and Configuration:

• Added a comprehensive configuration system using dataclasses in config.py, supporting YAML import/export and detailed report, analysis, table, statistics, and plot options. This enables flexible and reproducible report setups.
• Established a new CLI entrypoint in cli.py for generating reports, with argument parsing, config file support, and error handling, allowing command-line automation and integration.
• Updated the __init__.py to set up a dedicated Matplotlib config directory and expose all major config and workflow classes at the package level, improving import ergonomics and reproducibility.

Report Output Management:

• Introduced ReportPaths in paths.py to standardize and create all necessary output directories for tables, stats, figures, and logs, ensuring consistent file organization.
• Added a ResultRegistry in registry.py to track generated tables, figures, stats, HTML, warnings, errors, and runtime metadata, with JSON serialization for downstream consumption or debugging.

User Interface and Templates:

• Added new Jinja2 HTML templates for rendering figure tiles (figure_tile.html.j2) and a basic plots section (section_basic_plots.html.j2), providing a user-friendly, searchable, and interactive report interface for exploring generated outputs. [1] [2]
