Issue #2584 : Add Calculator conversions between JDE Julian and ISO dates

[mattcasters]

Fixes #2584

The Calculator transform can convert JD Edwards Julian dates (CYYDDD) to and from Hop dates, so this no longer needs a JavaScript workaround.

Two new calculations appear in the Calculator Calculation dropdown:

• Date A to JDE Julian (CYYDDD) (DATE_TO_JDE_JULIAN) → Integer
• JDE Julian A (CYYDDD) to Date (JDE_JULIAN_TO_DATE) → Date

CYYDDD matches the sample from the issue:

• C = century relative to 1900 (0 = 1900–1999, 1 = 2000–2099)
• YY = two-digit year
• DDD = day of year (001–366)

Examples: 95001 is 1995-01-01, 109001 is 2009-01-01, 111013 is 2011-01-13. Five-digit values such as 95001 are accepted. Julian input can be Integer, Number, or String.

Years before 1900 and invalid day-of-year values raise an error.

Also includes user-manual entries, sample pipeline calculator-jde-julian.hpl, unit tests, and an integration test.

Calculator module tests and apache-rat:check passed locally. Full mvn clean install apache-rat:check was not run locally.
