This commit introduces two new SQL functions: `fxBibSqlDuplicateUnitCount`, which counts the number of units sharing a `no_bib` for an event, and `fxBibSqlIsBibDuplicateAnomaly`, which checks for duplicate anomalies excluding legitimate team sharing. These functions enhance the existing bib management logic by improving the accuracy of duplicate detection. Additionally, the existing SQL queries in `fxInfosBibRange` and `fxBibAnomalyDuplicateBibs` are updated to utilize the new functions for better clarity and efficiency.
