chore(tenants): register the new local "mybank" tenant in the UI tenant list

Added 'mybank' to fineractPlatformTenantIds in all three places the tenant
selector reads it from, so the local database + tenant-store registration just
created (fineract_mybank, identifier "mybank", name "MyBank", copied from
lincpay's local connection settings onto a fresh empty schema) shows up as a
login option:

- src/assets/env.js (window['env'] default, read before Angular bootstraps)
- src/environments/environment.ts (dev build fallback)
- src/environments/environment.prod.ts (prod build fallback)

Each already listed utkarshbank, lincpay, utkarshnagari, testbank, humarwork,
default -- this only appends mybank, nothing else in the list changes.

.env.ts is the auto-generated build stamp (npm run env) and picked up
incidentally alongside; it carries no logic.

Not included in this commit: the fd-interest-posting / fd-maturity-report /
branch-day / shell.component.html changes sitting in the working tree are a
separate, unrelated, in-progress feature and are deliberately left out.
