Brings the FD interest posting approval UI and the latest UI work into dev-latest: - FD interest posting approval screens, posting period and GL-reconciled maturity interest - FD maturity approval UI added and then reverted (maturity now runs directly through the scheduler, no approval step) - "mybank" tenant registered in the UI tenant list - Animated boot splash and reusable loading screen - Compact navigation with grouped mega menus and branded loaders Conflict resolved: - src/environments/.env.ts: kept dev-latest's generated version/hash; the file is regenerated by `npm start` anyway. Also: prettier formatting of toolbar.component.html (already unformatted on dev-latest; formatting only, required by the pre-commit hook). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
