feat: Refactor tools and upgrade wazuh-client

This commit introduces a major refactoring of the tool implementation by splitting the tools into separate modules based on their domain (agents, alerts, rules, stats, vulnerabilities). This improves modularity and
maintainability.

Key changes:
- Upgraded wazuh-client to version 0.1.7 to leverage the new builder pattern for client instantiation.
- Refactored the main WazuhToolsServer to delegate tool calls to the new domain-specific tool modules.
- Created a tools module with submodules for each domain, each containing the relevant tool implementations and parameter structs.
- Updated the default limit for most tools from 100 to 300, while the vulnerability summary limit is set to 10,000 to ensure comprehensive scans.
- Removed a problematic manual test from the test script that was causing it to hang.
