feat: Preserve parameter data types for variable references in Expression Language

[BackendBits]

Pull Request

Summary

Preserve original data types for parameters that directly reference other parameters, instead of converting them to String.

If a parameter is a simple reference like ${MONGO_DB_PORT} or $MONGO_DB_PORT and the target value is an Integer, Long, or Boolean, the referencing parameter now keeps that type. Existing string/template behavior is unchanged.

Issue

No existing GitHub issue.

This is needed because direct references (e.g. DUMPS_MONGO_PORT: ${MONGO_DB_PORT}) were previously turned into strings, which can break schema validation and consumers expecting numeric/boolean values.

Breaking Change?

• Yes
• No

Behavior only changes for simple references to non-String values, and is backwards-compatible for all other cases.

Scope / Project

• Project: build_effective_set_generator_java
• Module: parameters-processor
• Files:
  • parameters-processor/src/main/java/org/qubership/cloud/parameters/processor/expression/ExpressionLanguage.java
  • parameters-processor/src/test/java/org/qubership/cloud/expression/ExpressionLanguageTest.java

Implementation Notes

• Detect pure parameter references (${VAR}, $VAR, <% VAR %>) and, when they resolve to a non-String value, return a new Parameter wrapping that value without going through template/string processing.
• Keep all other values (including strings and complex expressions) on the existing Jinjava/Groovy/escaping path.
• Fix removeEscaping so it only operates on String values, avoiding unintended conversion of numeric/boolean values to strings.

Tests / Evidence

• Updated/added unit tests in ExpressionLanguageTest to cover:
  • Integer, boolean, and long references using both ${VAR} and $VAR.
  • String references that should not change behavior.
• All tests in parameters-processor pass (ExpressionLanguageTest and related suites).
• Effective-set generation manually verified to produce correct numeric/boolean values (e.g. 27017, true, 604800000) instead of quoted strings in the generated deployment-parameters.yaml.

Additional Notes

None.
