Issue #1 - [BUG] IP addresses with whitespace cause SSH connection failures

[zenocross]

Description

When users input server IP addresses with leading or trailing whitespace, SSH connections fail because the whitespace is not trimmed before attempting the connection.

Current Behavior

• User enters IP address with whitespace (e.g., " 192.168.1.1 " or "192.168.1.1 ")
• System attempts SSH connection with untrimmed IP
• Connection fails with error
• User must re-enter IP without whitespace

Expected Behavior

• User enters IP address (with or without whitespace)
• System automatically trims whitespace
• SSH connection succeeds
• Better user experience with input forgiveness

Steps to Reproduce

1. Navigate to server configuration
2. Enter an IP address with leading/trailing spaces: " 192.168.1.1 "
3. Attempt to establish SSH connection
4. Connection fails due to invalid IP format

Proposed Solution

Add .trim() method to IP address input field before processing. This is a simple string manipulation that should be applied wherever IP addresses are collected from user input.

Technical Context

• Type: Input validation fix
• Files affected: Server configuration forms
• Solution: String trimming on IP address fields
