feat: Add FROG report generation to workflows (Resolves #21)

[dyrpsf]

Description

This PR addresses Issue #21 by adding an optional step to generate a FROG (Flux balance constraint Report Objective Generation) report at the end of the analysis pipeline[cite: 11].

Key Changes

• Configurations: Added the frog: False parameter to the hqtb YAML configuration files (default, advanced, and basic) under the analysis step.
• Core Logic: Updated the run function in src/specimen/hqtb/core/analysis.py to accept the generate_frog boolean.
• FROG Generation: Integrated the fbc_curation.run_frog function. It creates a dedicated FROG_report directory within the analysis output folder and saves the report there.
• Safe Import: Wrapped the fbc_curation import in a try-except block so that if a user hasn't installed the package, it gracefully logs an error and skips the step without crashing the entire workflow.
• Documentation: Removed the "future update" placeholder for FROG in the about-pipeline.rst documentation.

Testing

• Verified that the workflow continues without errors when fbc_curation is not installed (falls back to logging an error).
