largest cycle in statistics not being computed correctly

[suprajamannava17]

Overview:
There are several issues with the current statistics calculations on the application, particularly regarding the largest cycle, preperiodic cardinality, average resultant, and PC set values. These metrics are not computed or displayed accurately, leading to inconsistent data presentation and reduced user confidence in the data reliability. This issue aims to address these errors by adjusting the calculations for these metrics to align with the expected definitions and correct any discrepancies in data output.

Tasks:

1. Correct Largest Cycle Calculation:

• Update the calculation for largest cycle to reflect the maximum of the cycle lengths (periodic_cycles in the graph table), rather than the maximum of the cardinality.
• Verify that the updated calculation accurately displays the largest cycle length for each record.

2. Fix Preperiodic Cardinality Calculation:

• Adjust the preperiodic cardinality calculation to return the correct values.
• Example Issue: In the search for aut group card: 3, only one map is returned,
  1.7e1406dd.6d8da028.1 P1 → P1 4 [x4-8xy3 : 4x3y+4y4] 1.1.1.1
  with preperiodic cardinality listed incorrectly as 2 instead of 4.

Expected Behavior:
The statistics for the largest cycle and preperiodic cardinality should reflect accurate calculations as per the intended definitions. These metrics should be displayed correctly and consistently for each record in the graph table and rational preperiodic filter.

Acceptance Criteria:

• Largest Cycle displays the maximum of cycle lengths (periodic_cycles in the graph table) for each record, not the max of the cardinality.
• Preperiodic Cardinality displays accurately, including edge cases where previous calculations showed discrepancies.
