undergroundwires 851917e049 Refactor text utilities and expand their usage
This commit refactors existing text utility functions into the
application layer for broad reuse and integrates them across
the codebase. Initially, these utilities were confined to test
code, which limited their application.

Changes:

- Move text utilities to the application layer.
- Centralize text utilities into dedicated files for better
  maintainability.
- Improve robustness of utility functions with added type checks.
- Replace duplicated logic with centralized utility functions
  throughout the codebase.
- Expand unit tests to cover refactored code parts.

/*
A common mistake when working with yaml files to forget mentioning that a value should
be interpreted as multi-line string using "|".
E.g.
```
code: |-
echo Hello
echo World
```
If "|" is missing then the code is inlined like `echo Hello echo World``, which can be
unintended. This test checks for similar issues in collection yaml files.
These tests can be considered as "linter" more than "unit-test" and therefore can lead
to false-positives.
