Modify Registration URL Definition

[vikman90]

Parent Issue: #241

Description

The agent has two primary connections:

1. Registration
2. Server connection for event reporting and command queries.

Currently, these are defined in wazuh-agent.yml as:

agent:
  server_url: https://localhost:27000
  registration_url: https://localhost:55000

Proposal

Since registration is a one-time, on-demand operation initiated via CLI, we propose:

1. Removing the registration_url configuration option.
2. Introducing a new CLI parameter --url for registration operations.

Example Command

./wazuh-agent --config-file wazuh-agent.yml --register-agent --user wazuh --password topsecret --name dummy --url https://localhost:55000

We've not deleted the option entry at wazuh-agent.yml.
