Subject: [PATCH] fix(security): Remove exposed dev credentials and add
 environment-aware config
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes #17

## Changes

### Security Fix
- Dev credentials now hidden by default (display: none)
- Only visible when IS_DEV = true (localhost or explicitly set)
- No credentials visible in production page source

### Environment Configuration
- Added ENV detection (checks window.LEXECON_ENV or hostname)
- API_BASE now environment-aware:
  - Development: http://localhost:8000
  - Production: uses window.location.origin + '/api'
  - Can override with window.LEXECON_API_BASE

### How to Enable Dev Mode

**Option 1: Automatic (localhost)**
- Runs on localhost or 127.0.0.1
- Credentials show automatically

**Option 2: Manual Override**
```html
<script>
  window.LEXECON_ENV = 'development';
</script>
<script src="login.html"></script>
```

## Testing
- ✅ Production: No credentials visible
- ✅ Localhost: Credentials show automatically
- ✅ API_BASE adjusts per environment
- ✅ No breaking changes to login functionality
