feat(auth): implement send password reset email via smtp

[Gautam7352]

This commit implements the TODO: Send email with reset token step in the auth module.

It does so by:

• Creating a common email package with an SMTPService struct using the built-in net/smtp package.
• Adding standard SMTPHost, SMTPPort, SMTPUser, SMTPPass, and SMTPFrom config variables to config.go and .env.example.
• Initializing email.NewService(config) and injecting it into the auth service via the DI container.go.
• Updating the signature of auth.NewService() in related modules, tests, and handlers.
• Using s.emailService.SendPasswordResetEmail in ForgotPassword().
• Updating the Go version in go.mod to 1.25.0 to support github.com/labstack/echo/v5.
