Production hardening: Remove deprecations, optimize chain queries, enforce explicit configuration (#134)

Browse Source 
* Initial plan

* Fix onLimitReached deprecation in rate-limit middleware

- Replace deprecated onLimitReached callback with inline logging in handler
- Update tests to verify logging happens in the rate limit handler
- Remove onLimitReached from exports as it's no longer a separate function

Co-authored-by: onnwee <211922112+onnwee@users.noreply.github.com>

* Fix fromBlock: 0 in event queries for better performance

- Replace fromBlock: 0 with smart default (last 1M blocks)
- Add REGISTRY_START_BLOCK env var for configurable starting block
- Update make-proof.ts, verification-jobs.routes.ts, and verification-queue.service.ts
- Document new env variable in .env.example

Co-authored-by: onnwee <211922112+onnwee@users.noreply.github.com>

* Remove hardcoded testnet RPC fallback for production safety

- Replace testnet fallbacks with proper error handling when RPC_URL is not configured
- Update registry.service.ts, blockchain.service.ts to throw errors if RPC_URL missing
- Update CLI scripts (verify.ts, register.ts, make-proof.ts) to fail fast without RPC_URL
- Update API routes to return 503 error when RPC_URL is not configured
- Update .env.example to emphasize RPC_URL is required

Co-authored-by: onnwee <211922112+onnwee@users.noreply.github.com>

* Add documentation for dual Prisma generators and pin Redis version

- Add comprehensive comments in schema.prisma explaining dual generator setup
- Document why both generators are needed (API vs Next.js web app)
- Pin Redis version to 7.2-alpine in all docker-compose files for reproducibility
- Update docker-compose.yml, docker-compose.production.yml, and docker-compose.staging.yml

Co-authored-by: onnwee <211922112+onnwee@users.noreply.github.com>

* Address code review feedback - add validation for REGISTRY_START_BLOCK

- Add proper validation for parseInt to handle NaN cases
- Ensure REGISTRY_START_BLOCK is validated before use
- Add comment explaining intentional empty catch block
- Prevents invalid block numbers from breaking event queries

Co-authored-by: onnwee <211922112+onnwee@users.noreply.github.com>

* Refactor block range validation into shared utility function

- Create block-range.util.ts with getStartBlock helper
- Extract duplicated validation logic from make-proof.ts, verification-jobs.routes.ts, and verification-queue.service.ts
- Improves code maintainability and ensures consistent validation
- Add comprehensive JSDoc documentation

Co-authored-by: onnwee <211922112+onnwee@users.noreply.github.com>

* Add comprehensive test coverage for block-range utility

- Create test/utils/block-range.util.test.ts following existing test patterns
- Test valid REGISTRY_START_BLOCK values (positive, zero, large numbers)
- Test invalid inputs (NaN, negative, empty string, whitespace)
- Test default fallback behavior (current block - 1M)
- Test edge cases (low block numbers, decimals, provider errors)
- 15 test cases covering all code paths and validation logic

// This file contains the Prisma schema definition for Internet-ID
//
// DUAL GENERATOR SETUP:
// This schema uses two Prisma Client generators for different parts of the application:
//
// 1. "client" - Default generator for API/scripts (outputs to root node_modules)
// Used by: Express API server, CLI scripts, verification workers, queue services
// Location: node_modules/.prisma/client
//
// 2. "client-web" - Web app generator (outputs to web/node_modules)
// Used by: Next.js web application (web/ directory)
// Location: web/node_modules/.prisma/client
//
// WHY TWO GENERATORS?
// - Next.js app runs in a separate process with its own node_modules
// - The web app needs Prisma Client in its node_modules for deployment
// - API server and scripts share the root Prisma Client
// - This avoids module resolution issues and keeps deployments clean
//
// IMPORTANT: Both generators read from the same schema and database
// Run `npm run db:generate` to regenerate both Prisma Clients after schema changes
// Default generator for API/scripts (root node_modules)
