Adds the frontend half of the per-tenant menu-access ceiling (TenantMenuAccessApiResource on the backend): a bank cannot show a top-nav section the platform operator has capped, no matter what any role inside that tenant grants itself — closing the gap where a role carrying ALL_FUNCTIONS (as "Clerk" was found to, in two tenants this session) bypassed every ordinary MENU_.../SIDEBAR_... permission check. - tenant-menu-access.service.ts: loads the current tenant's list once, into a plain Set (not an Observable the directive would have to subscribe to, since mifosxHasPermission's setter runs synchronously). A failed load is treated as "nothing disabled" so a network hiccup on login never hides the whole nav. - has-permission.directive.ts: checks the tenant's ceiling first, ahead of the ALL_FUNCTIONS bypass — that ordering is the actual fix. - shell.component.ts/html: the nav now waits on the list being loaded before rendering at all, so a disabled menu is never shown and then hidden a moment later. - New standalone platform-admin/menu-access screen (#/platform-admin/ menu-access), reachable without logging in — its own X-Api-Key is the real boundary, checked on the backend, not this route. Lets the operator pick any tenant and toggle its menu list. Redesigned per request: full-width layout, icon-matched toggle tiles (same icon per item as the real nav), live enabled-count, connection status. - Loan Origination and Investment now use their own MENU_LOAN_ORIGINATION / MENU_INVESTMENT codes (see backend 0542) instead of sharing MENU_ADVANCES / MENU_RBI, so all 27 nav items are independently controllable from this screen. Also: src/assets/env.js — restored 'socity_bank' to fineractPlatformTenantIds. The tenant now exists in the tenant-store database; the comment explaining its earlier removal was stale.
