test: verify database stack migration

[CristianAmbrosini]

Test PR to verify sc_rds DatabaseStack works on dev18.

[sonar-review-dev18]

Summary

This PR adds a new string_utils.py module with three string manipulation utility functions: reverse(), capitalize_words(), and truncate() with configurable suffix.

Note: The PR title and description reference a database stack migration verification (sc_rds DatabaseStack on dev18), but the actual code change is unrelated to databases — it's a new utility module. This appears to be either a mislabeled PR or the description was copied from elsewhere. Clarify with the author what this PR is actually testing.

❌ The last analysis has failed.

What reviewers should know

What to review:

• The three utility functions are straightforward string operations with type hints
• Focus on whether these functions are actually needed, or if they duplicate existing stdlib/third-party alternatives (Python's str.title() is similar to capitalize_words(), for example)
• Check if this module integrates with or is tested by the rest of the codebase — no tests or imports are visible in this diff

Gotcha: The PR metadata doesn't match the code. Either this is intentionally testing webhook/enablement mechanisms with dummy code, or there's confusion about what this PR contains. Clarify the actual intent before approving.

One bug in truncate() that needs fixing before merge.

🗣️ Give feedback

[sonar-review-dev18]

Bug: When max_length < len(suffix), the slice index becomes negative, so Python interprets it as an offset from the end of the string. The result is a string that exceeds max_length.

Example: truncate("hello", 2, "...") → s[:-1] + "..." → "hell..." (7 chars, not 2).

Add a guard before the slice to handle this case:

Suggested change

	if len(s) <= max_length:
	return s
	return s[: max_length - len(suffix)] + suffix
	if len(s) <= max_length:
	return s
	if max_length <= len(suffix):
	return suffix[:max_length]
	return s[: max_length - len(suffix)] + suffix

Summary

This PR adds a new string_utils.py module with three utility functions: reverse(), capitalize_words(), and truncate().

Note: The PR title and description reference database stack migration verification, but the actual changes are a new string utilities module. This appears to be a test/validation PR (as indicated by the commit message "trigger webhook for enablement test"), so the metadata and code changes may not be directly related.

What reviewers should know

What to review:

• The string utility functions in string_utils.py are straightforward Python helpers with basic type hints
• The truncate() function uses a configurable suffix (defaults to "...") which may be worth validating for edge cases

Context for reviewers:
Given the "enablement test" nature of this PR and the mismatch between the PR metadata (database stack verification) and actual code changes, verify whether this is intentional test infrastructure or if the PR description needs updating. If this is a validation PR, the string utils are likely incidental to the real purpose.

This commit only adds a trailing newline — no logic changes. The previously flagged bug in truncate is still open.
