fields. AppliesTo(country, regime) is the matching rule the new lookup
methods filter through: a row matches when its Country equals the
court's country OR its Regime equals the court's regime. UPC LD München
(DE+UPC) sees DE federal + UPC vacations; LG München (DE+"") sees only
DE federal; UPC LD Paris (FR+UPC) sees FR + UPC. germanFederalHolidays
fallback now country-tagged 'DE' so the per-country filter applies it
only to DE-jurisdictional callers.
Public service methods (IsHoliday, IsNonWorkingDay, AdjustForNonWorking
Days, AdjustForNonWorkingDaysWithReason, findVacationBlock) all take
(country, regime). Cache stays year-keyed — single DB hit per year, all
courts touching that year share it.
New CourtService loads paliad.courts once + answers Lookup(id),
CountryRegime(id, defaultCountry, defaultRegime), All(), ByCourtType(t).
FristenrechnerService.CalcOptions / CalcRuleParams gain CourtID;
EventDeadlineService.Calculate gains courtID. When courtID is empty,
DefaultsForJurisdiction maps the proceeding's existing jurisdiction
column to a sensible (country, regime) default — UPC proceedings get
(DE, UPC), everything else gets DE-only — preserving today's behaviour
for callers that don't yet send a court.
Tests: new TestAppliesTo_CountryRegimeFilter + TestAppliesTo_Rules
cover the cross-product of (DE court / UPC LD München / UPC LD Paris /
LG München) × (DE federal / UPC vacation / FR holiday). Existing tests
threaded through with ('DE', 'UPC') to preserve behaviour they were
written to lock.
