feat(fiu): add Head Office / Branch-wise scoping; remove reconciliation nav dots

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.
