refactor(config): externalize rpcAccessProducts to config/rpc_products.yaml

The Chain 138 RPC access product catalog (core-rpc / alltra-rpc / thirdweb-rpc, each with VMID + HTTP/WS URL + tier + billing model + use cases + management features) used to be a hardcoded 50-line Go literal in api/rest/auth.go. The review flagged this as the biggest source of 'magic constants in source' in the backend: changing a partner URL, a VMID, or a billing model required a Go recompile, and the internal 192.168.11.x CIDR endpoints were baked into the binary. This PR moves the catalog to backend/config/rpc_products.yaml and adds a lazy loader so every call site reads from the YAML on first use. New files: backend/config/rpc_products.yaml source of truth backend/api/rest/rpc_products_config.go loader + fallback defaults backend/api/rest/rpc_products_config_test.go unit tests Loader path-resolution order (first hit wins): 1. $RPC_PRODUCTS_PATH (absolute or cwd-relative) 2. $EXPLORER_BACKEND_DIR/config/rpc_products.yaml 3. <cwd>/backend/config/rpc_products.yaml 4. <cwd>/config/rpc_products.yaml 5. compiled-in defaultRPCAccessProducts fallback (logs a WARNING) Validation on load: - every product must have a non-empty slug, - every product must have a non-empty http_url, - slugs must be unique across the catalog. A malformed YAML causes a WARNING + fallback to defaults, never a silent empty product list. Call-site changes in auth.go: - 'var rpcAccessProducts []accessProduct' (literal) -> func rpcAccessProducts() []accessProduct (forwards to the lazy loader). - Both existing consumers (/api/v1/access/products handler at line ~369 and findAccessProduct() at line ~627) now call the function. Zero other behavioural changes; the JSON shape of the response is byte-identical. Tests added: - TestLoadRPCAccessProductsFromRepoDefault: confirms the shipped YAML loads, produces >=3 products, and contains the 3 expected slugs with non-empty http_url. - TestLoadRPCAccessProductsRejectsDuplicateSlug. - TestLoadRPCAccessProductsRejectsMissingHTTPURL. Verification: go build ./... clean go vet ./... clean go test ./api/rest/ PASS (new + existing) go mod tidy pulled yaml.v3 from indirect to direct Advances completion criterion 7 (no magic constants): 'Chain 138 access products / VMIDs / provider URLs live in a YAML that operators can change without a rebuild; internal CIDRs are no longer required to be present in source.'

-# 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`.
-
-### Env vars
-
-| 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.
