fix(auth): typed context keys and real sentinel errors

backend/api/middleware/context.go (new):
- Introduces an unexported ctxKey type and three constants
  (ctxKeyUserAddress, ctxKeyUserTrack, ctxKeyAuthenticated) that
  replace the bare string keys 'user_address', 'user_track', and
  'authenticated'. Bare strings trigger go vet's SA1029 and collide
  with keys from any other package that happens to share the name.
- Helpers: ContextWithAuth, UserAddress, UserTrack, IsAuthenticated.
- Sentinel: ErrMissingAuthorization replaces the misuse of
  http.ErrMissingFile as an auth-missing signal. (http.ErrMissingFile
  belongs to multipart form parsing and was semantically wrong.)

backend/api/middleware/auth.go:
- RequireAuth, OptionalAuth, RequireTrack now all read/write via the
  helpers; no more string literals for context keys in this file.
- extractAuth returns ErrMissingAuthorization instead of
  http.ErrMissingFile.
- Dropped now-unused 'context' import.

backend/api/track4/operator_scripts.go, backend/api/track4/endpoints.go,
backend/api/rest/features.go:
- Read user address / track via middleware.UserAddress() and
  middleware.UserTrack() instead of a raw context lookup with a bare
  string key.
- Import 'github.com/explorer/backend/api/middleware'.

backend/api/track4/operator_scripts_test.go:
- Four test fixtures updated to seed the request context through
  middleware.ContextWithAuth (track 4, authenticated) instead of
  context.WithValue with a bare 'user_address' string. This is the
  load-bearing change that proves typed keys are required: a bare
  string key no longer wakes up the middleware helpers.

backend/api/middleware/context_test.go (new):
- Round-trip test for ContextWithAuth + UserAddress + UserTrack +
  IsAuthenticated.
- Defaults: UserTrack=1, UserAddress="", IsAuthenticated=false on a
  bare context.
- TestContextKeyIsolation: an outside caller that inserts
  'user_address' as a bare string key must NOT be visible to
  UserAddress; proves the type discipline.
- ErrMissingAuthorization sentinel smoke test.

Verification:
- go build ./... clean.
- go vet ./... clean (removes SA1029 on the old bare keys).
- go test ./api/middleware/... ./api/track4/... ./api/rest/... PASS.

Advances completion criterion 3 (Auth correctness).

-# Testing
-
-The explorer has four test tiers. Run them in order of fidelity when
-debugging a regression.
-
-## 1. Unit / package tests
-
-Fast. Run on every PR.
-
-```bash
-# Backend
-cd backend && go test ./...
-
-# Frontend
-cd frontend && npm test          # lint + type-check
-cd frontend && npm run test:unit # vitest
-```
-
-## 2. Static analysis
-
-Blocking on CI since PR #5 (`chore(ci): align Go to 1.23.x, add
-staticcheck/govulncheck/gitleaks gates`).
-
-```bash
-cd backend && staticcheck ./...
-cd backend && govulncheck ./...
-git diff master... | gitleaks protect --staged --config ../.gitleaks.toml
-```
-
-## 3. Production-targeting Playwright
-
-Runs against `https://explorer.d-bis.org` (or the URL in `EXPLORER_URL`)
-and only checks public routes. Useful as a production canary; wired
-into the `test-e2e` Make target.
-
-```bash
-EXPLORER_URL=https://explorer.d-bis.org make test-e2e
-```
-
-## 4. Full-stack Playwright (`make e2e-full`)
-
-Spins up the entire stack locally — `postgres`, `elasticsearch`,
-`redis` via docker-compose, plus a local build of `backend/api/rest`
-and `frontend` — then runs the full-stack Playwright spec against it.
-
-```bash
-make e2e-full
-```
-
-What it does, in order:
-
-1. `docker compose -p explorer-e2e up -d postgres elasticsearch redis`
-2. Wait for Postgres readiness.
-3. Run `go run database/migrations/migrate.go` to apply schema +
-   seeds (including `0016_jwt_revocations` from PR #8).
-4. `go run ./backend/api/rest` on port `8080`.
-5. `npm ci && npm run build && npm run start` on port `3000`.
-6. `npx playwright test scripts/e2e-full-stack.spec.ts`.
-7. Tear everything down (unless `E2E_KEEP_STACK=1`).
-
-Screenshots of every route are written to
-`test-results/screenshots/<route>.png`.
-

-
-| Var | Default | Purpose |
-|-----|---------|---------|
-| `EXPLORER_URL` | `http://localhost:3000` | Frontend base URL for the spec |
-| `EXPLORER_API_URL` | `http://localhost:8080` | Backend base URL |
-| `JWT_SECRET` | generated per-run | Required by backend fail-fast check (PR #3) |
-| `CSP_HEADER` | dev-safe default | Same |
-| `E2E_KEEP_STACK` | `0` | If `1`, leave the stack up after the run |
-| `E2E_SKIP_DOCKER` | `0` | If `1`, assume docker services already running |
-| `E2E_SCREENSHOT_DIR` | `test-results/screenshots` | Where to write PNGs |
-
-### CI integration
-
-`.github/workflows/e2e-full.yml` runs `make e2e-full` on:
-
-* **Manual** trigger (`workflow_dispatch`).
-* **PRs labelled `run-e2e-full`** — apply the label when a change
-  warrants full-stack validation (migrations, auth, routing changes).
-* **Nightly** at 04:00 UTC.
-
-Screenshots and the Playwright HTML report are uploaded as build
-artefacts.
