Appends accountsList, createAccount, toggleAccount, and resetAccountPassword
to adminAuth.server.controller.js, adds the accounts-list view, and wires
the /admin/accounts* routes behind requireLogin + requireAdmin.

createTransaction now stamps createdByUsername from the session. listTransactions
scopes results to the logged-in staff's own transactions, or (for admins) all
transactions with an optional ?staff= filter sourced from real AdminUser
records - the filter is ignored for non-admin sessions so staff cannot view
another account's data by editing the query string. Transaction routes now use
requireLogin instead of basicAuth, which is now unused and deleted.

Adds AdminTransaction.createdByUsername (default null) so future
permission-scoped views can attribute data to a user, plus a new
app/libs/adminBootstrap.js that seeds the first admin account from
ADMIN_USER/ADMIN_PASSWORD on boot and backfills any pre-existing
transaction lacking createdByUsername to that admin. Wired into
server.js's mongoose 'open' handler. Idempotent across repeated boots.

Implement two authentication and authorization middlewares:
- requireLogin: checks req.session.userId and responds with 302 redirect to /admin/login
  for HTML requests, or 401 JSON for API requests
- requireAdmin: checks req.session.role === "admin" and responds with 403 for unauthorized access

Add passwordHash utility module wrapping bcryptjs for secure password hashing, and AdminUser Mongoose model with username (unique, lowercase), passwordHash, role (admin/staff), and active fields.

Adds listTransactions controller action and its Swig view, and creates
app/routes/admin.server.routes.js to finally wire every admin controller
function (Tasks 7-9) to real HTTP routes via the app's glob-based route
loader. basicAuth protects /admin/transactions and /admin/transactions/new;
the pay page, epay return, and epay IPN endpoints stay public.

Implements Task 7: newTransactionForm and createTransaction controller functions with supporting view.
- Controller generates merTrxId and transCode with UUID-based unique suffix
- Signs transaction using epaySign.signRequest
- Persists AdminTransaction record to MongoDB
- Returns JSON response with code 00/99 and payment URL
- View provides HTML form to submit customer data and display payment link

Implements signRequest and signResponse functions that compute
MegaPay/Epay HMAC-SHA256 signatures per MGP_Merchant_Interface
specification sections 5.1 and 5.3. These functions will be consumed
by Tasks 7 and 9 of the admin transaction management feature.

Add mongoUri and admin.{user,password} config keys to config/env/all.js
for Task 2 admin transaction management feature. Follows existing env var
pattern used for payment provider credentials. Default mongoUri points to
Docker service; admin credentials read from ADMIN_USER/ADMIN_PASSWORD env.

11 bite-sized tasks: Docker Compose mongo service, config, Mongoose
connection, shared MegaPay signing helper, model, Basic Auth middleware,
create/pay/return/ipn/history endpoints, final Docker integration test.

New self-contained module for staff to create Epay payment links for
customers and track their status, kept separate from the just-stabilized
/epay/* customer-facing flow to avoid regression risk.
