v1.3.23 CRAN release

jstable 1.3.23

• Fix: svyregress.display no longer errors when pcut.univariate selects a single variable (prevents dimension dropping).
• Fix: svycox.display now preserves matrix dimensions when subsetting to a single selected term with pcut.univariate.

jstable 1.3.22

• Fix: CreateTableOneJS and CreateTableOne2 now have correct headers for overall and strata columns.

jstable 1.3.21

• Fix: TableSubgroupCox and TableSubgroupMultiCox now correctly maintain Count and Percent from original data in competing risk analysis
• When data_original is provided, Count and Percent are calculated from the original data instead of finegray-transformed data
• This ensures accurate sample sizes and percentages while cumulative incidence is still calculated using competing risk methods
