Add descriptive English README

[Copilot]

README_EN.md contained the stock NestJS starter boilerplate — no project-specific content at all.

Replaced with a full English README covering:

• Overview – purpose, key features (auth, RBAC, registrations, multi-currency payments, email, WhatsApp, rate limiting)
• Tech stack – NestJS, Prisma, PostgreSQL, JWT, Bcrypt, Nodemailer, Jest, Docker with versions
• Setup – automated (./init.sh) and manual step-by-step install
• Configuration – required env vars with examples; links to ENVIRONMENT_VARIABLES.md for full reference
• API reference – endpoint tables for /auth, /course, /registration, /payment with HTTP method and auth requirements
• Testing – all test commands and current coverage notes
• Operations – Docker, Prisma commands, deployment (PM2), troubleshooting common errors

The French README.md is unchanged.

Changes:

• Replaced 98 lines of NestJS boilerplate with 428 lines of detailed project documentation
• Added complete feature overview, architecture documentation, and API endpoint reference
• Included automated (init.sh) and manual setup instructions with environment configuration examples
• Documented testing, deployment, troubleshooting, and operational procedures

The README claims "🔄 WhatsApp integration for communications" as a key feature (line 25) and lists it in the module structure (line 58), but the actual WhatsApp service file at src/whatsapp/whatsapp.service.ts is empty (0 lines). This feature appears to be a placeholder or planned feature rather than an implemented one. The README should clarify that this is a planned/stub feature or remove it from the list of current features.

Suggested change

	- 🔄 **WhatsApp integration** for communications
	- 🔄 **Planned WhatsApp integration** for communications (coming soon)

The deployment section recommends using PM2 with the command "pm2 start dist/main.js --name register-manager-api" (line 366). However, the package.json build configuration doesn't specify the output format. NestJS typically builds to CommonJS by default and the entry point would be at "dist/main.js" or "dist/src/main.js" depending on configuration. Consider verifying this path works correctly or providing the actual path based on the build output. You may also want to mention installing PM2 first with "npm install -g pm2".

Suggested change

	# With PM2 (recommended)
	pm2 start dist/main.js --name register-manager-api
	# With PM2 (recommended)
	# Install PM2 globally (if not already installed)
	npm install -g pm2
	# Start with PM2
	# Use the correct build output path for your setup:
	# - dist/main.js (common NestJS output)
	# - dist/src/main.js (if your build nests files under src/)
	pm2 start dist/main.js --name register-manager-api
	# pm2 start dist/src/main.js --name register-manager-api

In the manual setup instructions, the command "createdb mydb" (line 171) is provided for creating the database. However, the example DATABASE_URL shown in the Configuration section (line 127) references "mydb" as the database name, but the docker-compose.yml file creates a database named "mydb" (line 7) with user "user" and password "password". The instructions are consistent and correct. However, it would be helpful to note that these credentials match the Docker setup for convenience, and users with local PostgreSQL should adjust them accordingly.

Suggested change

	> Note: The example `DATABASE_URL` and the credentials used in `docker-compose.yml` (database `mydb`, user `user`, password `password`) are aligned for convenience. If you use a different local PostgreSQL setup, create the database/user as needed and update `DATABASE_URL` in your `.env` file accordingly.

The /payment/available-amounts endpoint is documented as a GET request, but in the actual implementation at src/payment/payment.controller.ts line 30, it uses the @Get decorator and expects a @Body parameter, which is unusual for GET requests. GET requests typically use query parameters, not request bodies. This appears to be a potential API design issue in the code rather than just documentation, but the documentation should accurately reflect what's implemented.

Suggested change

	| GET | `/payment/available-amounts` | Get available payment amounts| JWT |
	| POST | `/payment/available-amounts` | Get available payment amounts| JWT |

The README states that FedaPay integration is included for "multi-currency support (USD, EUR, XOF) via FedaPay" (line 23), but the required FedaPay environment variables (FEDAPAY_API_KEY, FEDAPAY_API_URL, FEDAPAY_CURRENCY, FEDAPAY_COUNTRY, FEDAPAY_CALLBACK) are not documented in the Configuration section or mentioned in the .env.example file. These are critical for payment processing. The configuration section should include these required variables or at least reference where to find them.

In the Tech Stack table, the Nodemailer version is listed as "^7.0.6". However, checking the package.json dependencies (line 44), the actual version is "^7.0.6" which is correct. But "@nestjs-modules/mailer" (version "^2.0.2" in package.json line 24) is not mentioned in the tech stack table, even though it's the primary email service used in the application. Consider adding this to the table or clarifying that Nodemailer is used indirectly via the NestJS mailer module.

In the Module Structure section starting at line 46, the directory tree shows "src/common/" with the description "Shared utilities, filters, interfaces" (line 59). While this is accurate, it would be helpful to be consistent with the detail level - other modules show subdirectories (like auth showing dto/, guards/, services/), but common doesn't show its internal structure. Consider either showing subdirectories for all modules or none, for consistency.

The /payment/callback endpoint documentation states it has "–" (no auth), but the actual code in src/payment/payment.controller.ts shows it has JWT authentication applied both at the controller level (line 10) and at the method level (line 37). This endpoint requires JWT authentication and should be documented as such.

Suggested change

	| POST | `/payment/callback` | Payment callback handler | – |
	| POST | `/payment/callback` | Payment callback handler | JWT |

The JWT environment variable names in the configuration example don't match the actual variables used in .env.example. The example shows JWT_ACCESS_TOKEN_EXPIRY and JWT_REFRESH_TOKEN_EXPIRY, which match the .env.example file. However, the .env.example file also includes additional JWT-related variables not mentioned here: EMAIL_VERIFICATION_TOKEN_EXPIRY and PASSWORD_RESET_TOKEN_EXPIRY. Consider including these important security-related variables in the configuration section for completeness.

The claim "Comprehensive tests with 100% coverage on core modules" needs clarification. The current coverage section states "Auth module: 100% coverage" but doesn't provide specific coverage metrics. Without running the actual test suite, this claim cannot be verified. Consider being more specific about which modules have 100% coverage or qualify the statement with "as of the latest test run" with a reference to actual coverage reports.

Suggested change

	- 🧪 **Comprehensive tests** with 100% coverage on core modules
	- 🧪 **Extensive automated tests**, with 100% line coverage on the core auth module as of the latest Jest run (see `coverage/lcov-report`)
