Test/ide pi config generator

[kilqwe]

Purpose / Description

The PiAdapter config in observal-server/services/ide/pi.py did not have dedicated unit tests. This PR adds the unit tests.

Fixes

• Fixes test: add unit tests for Pi config generator #1381

Approach

Created test_ide_pi_config_generator.py with 15 unit tests that covers:

• MCP config generation produces valid JSON with correct mcpServers schema.
• Skill file generation returns correctly structured skill components.
• Rules file (AGENTS.md) generation writes correct path and content.
• Edge cases: empty/None inputs produce empty list (dict) with no crash.
