FIU: adds a branch selector (Head Office sees all/drills into one branch, a branch-level login is locked to its own branch) scoping the CTR/STR tabs, dashboard KPIs and header. A FIU_BRANCH_CODE_TO_CANONICAL map bridges the module's internal FINnet branch codes to the app-wide BranchMaster codes. Live backend-driven AML alerts/cases are unchanged (no branch field to scope by). Shell: removes the "working nav" green-dot indicator from the Reconciliation mega-menu's 17 report links per request.
