feat(docs): Add database migration instructions and Neon setup details

- Introduced comprehensive sections on database migrations in the README files for English and Vietnamese documentation, including prerequisites, migration creation, and application steps.
- Added instructions for setting up the Neon database, including connection string configuration in `appsettings.Development.json`.
- Updated the `appsettings.Development.json` file with a default connection string for the Neon database and added Redis configuration.
- Included additional EF Core commands for managing migrations in the Vietnamese documentation.

+```bash
+dotnet ef migrations add <MigrationName> \

+### Neon Database Setup
+
+1. Create database on [Neon Console](https://console.neon.tech)
+2. Copy connection string
+3. Update `appsettings.Development.json`:
+```json
+{
+  "ConnectionStrings": {
+    "DefaultConnection": "Host=<host>;Port=5432;Database=<db>;Username=<user>;Password=<pass>;SSL Mode=Require"

+### Yêu Cầu
+
+```bash
+# Cài đặt EF Core tools (một lần)
+dotnet tool install --global dotnet-ef
+```
+
+### Tạo Migration
+
+```bash
+# Tạo migration mới
+dotnet ef migrations add <TenMigration> \
+  --project src/IamService.Infrastructure \
+  --startup-project src/IamService.API
+```

+dotnet ef database update \
+  --project src/IamService.Infrastructure \
+  --startup-project src/IamService.API
+```
+
+### Các Lệnh Khác

+### Thiết Lập Neon Database
+
+1. Tạo database trên [Neon Console](https://console.neon.tech)
+2. Sao chép connection string
+3. Cập nhật `appsettings.Development.json`:
+```json
+{
+  "ConnectionStrings": {
+    "DefaultConnection": "Host=<host>;Port=5432;Database=<db>;Username=<user>;Password=<pass>;SSL Mode=Require"
