test: verify enablement flow

[CristianAmbrosini]

Test PR #47 to trigger upsertInstallationId after DB restart.

[sonar-review-dev18]

Summary

Adds a new palindrome checker utility function. The is_palindrome() function takes a string, normalizes it by converting to lowercase and removing spaces, then checks if it equals its reverse. This appears to be a simple test PR to verify the repository setup and CI flow.

What reviewers should know

What's being added:

• New file: palindrome.py with a single reusable function
• The function handles basic text normalization before checking palindrome status
• No tests, dependencies, or documentation are included

For reviewers:

• Note that the PR description mentions "upsertInstallationId" and "DB restart", but the actual code is a standalone palindrome checker—these may be unrelated or the description may not accurately reflect the changes
• The implementation is straightforward and has no external dependencies
• Consider whether this function should be tested before merge, and whether documentation or a test module should be added

Simple, clean addition. One behavior gap worth addressing before this function is used more broadly.

The normalization strips spaces but not other non-alphanumeric characters (punctuation, tabs, hyphens, etc.). The canonical palindrome example "A man, a plan, a canal: Panama" returns False with the current implementation.

If the function is meant to handle natural-language strings, the cleaned step should strip all non-alphanumeric characters instead of just spaces.

Suggested change

	cleaned = s.lower().replace(" ", "")
	cleaned = "".join(c for c in s.lower() if c.isalnum())
