Add pure Jalali calendar math, JalaliDate class, and BrnJalaliDateAdapter with tests.

* refactor: clean up jalali date-time code
- Deduplicate JALALI_MONTHS array in calendar i18n files
- snake_case to camelCase in PersianDate (gregorianDaysInMonth, jalaliDaysInMonth)
- Expand cryptic param names (j_y to jalaliYear, g_y to gregorianYear, etc.)
- Remove parseInt() no-ops on typed number params
- Remove getMonthName (i18n concern, not calendrical)
- Destructure tuples with descriptive names across adapter/date/persian-date
- Fix month+day add drift: clamp day after month step before day arithmetic
* style: fix long line formatting to pass nx format check
* fix(date-picker): resolve merge conflicts from upstream and stashed changes
Merge descriptive variable names (_constrain, parseInt, getMonthName,
full descriptive names) with upstream descriptive names. All tests pass.
