createEvent never called logAdminAction, even though 1.10.0 already
listed event_created as a filterable action on the audit-log page —
only updateEvent/deleteEvent actually logged. Event creation is now
logged the same way, at every return path including the legacy
pre-migration retry branches.
Also adds a "Back to dashboard" link to Admin -> Audit log, matching
the existing back-link pattern on the Cashup page.

express, cors, and @prisma/client were required at the top of
backend/src/index.js before Sentry.init() ran, so Sentry's
auto-instrumentation (which patches those modules via a require hook)
missed them — startup logged "[Sentry] express is not instrumented".
Sentry.init() now runs immediately after dotenv.config(), before any
of the libraries it instruments are required.

Path traversal (CWE-22/CWE-73): event-image, branding (logo/favicon),
and event-attachment uploads built the saved filename from the
client-supplied original filename with no sanitization, and multer's
diskStorage joins that straight into the destination path. A crafted
filename containing `../` sequences could write the uploaded file
anywhere the server process has write access — reachable by any
supervisor-level account, and briefly pre-auth via the branding
uploads during initial /setup. Filenames are now always server-
generated (random bytes + validated extension); the original name is
kept only as display metadata.
Dependencies: express-rate-limit was declared only at the repo root
despite being required directly by backend/src/index.js, so a plain
`cd backend && npm install` (per the deployment doc) would never
install it — moved it into backend/package.json. Bumped next off a
version affected by a critical unauthenticated RCE (React Flight
protocol) and switched it from an exact pin to a caret range so future
patches install automatically. Bumped multer/nodemailer/jsonwebtoken/
uuid to patched versions, with an override forcing the vulnerable
nested uuid inside exceljs and the vulnerable postcss bundled inside
next to the patched versions too. `npm audit` is now clean (0
vulnerabilities) across root, backend, and frontend.
Hardening: jwt.verify() now pins algorithms: ['HS256'] instead of
trusting the token header; /uploads now serves with a restrictive CSP
and X-Content-Type-Options: nosniff so an uploaded SVG containing
<script> can't execute if opened directly.
Verified: backend's Jest suite passes, the backend boots and serves
real requests on the bumped deps, and `next build` compiles/type-
checks cleanly on the bumped frontend deps.
