Extends RegionService, RegionRepository, and RegionController with the
endpoints from mainPlan.md sec 2 beyond plain CRUD: setRegionalTarget,
setRegionalBudget, mapAgencyToRegion, setRegionalTaxRule,
getRegionHierarchy, and getRegionDashboard. Target/budget/tax-rule
mutation is gated to users with region scope at RegionalManager level
or RegionalAgency level across all regions; mapAgencyToRegion links an
existing User holding the RegionalAgency role rather than introducing
a separate agency entity, matching the convention already used by
Claim.FK_AgencyUserId elsewhere in the codebase.
