fix: resolve 5 SonarQube code quality issues

[sonarqube-agent]

This PR was automatically created by the Remediation Agent's Scheduled backlog remediation feature.

This PR addresses 5 minor SonarQube findings across the codebase: replaced String.match() calls with RegExp.exec() for better performance, renamed two interface identifiers from lowercase to PascalCase to follow naming conventions, and converted a traditional for loop to for...of syntax for improved readability. These changes maintain semantic equivalence while improving code quality and adherence to TypeScript best practices.

Fixed Issues

typescript:S6594 - Use the "RegExp.exec()" method instead. • MINOR • View issue

Location: test/cypress/support/commands.ts:36

Why is this an issue?

String.match() behaves the same way as RegExp.exec() when the regular expression does not include the global flag g. While they work the same, RegExp.exec() can be slightly faster than String.match(). Therefore, it should be preferred for better performance.

What changed

This hunk replaces context.email.match(/\S+@\S+\.\S+/) with /\S+@\S+\.\S+/.exec(context.email), converting from String.match() to RegExp.exec(). Since the regex does not use the global flag g, these two calls are semantically equivalent, but RegExp.exec() is preferred for slightly better performance. This directly addresses the code smell about using String.match() where RegExp.exec() should be used instead.

What changed

This hunk replaces source.match(regex) with new RegExp(regex).exec(source), converting from String.match() to RegExp.exec(). The static analysis rule flags String.match() as a code smell because when the regex doesn't use the global flag g, RegExp.exec() is semantically equivalent but can be slightly faster. The change restructures the call so the RegExp object calls .exec() with the string as the argument, rather than the string calling .match() with the regex pattern.

typescript:S101 - Rename interface "result" to match the regular expression ^[A-Z][a-zA-Z0-9]*$. • MINOR • View issue

Location: frontend/src/app/Services/code-fixes.service.ts:7

Why is this an issue?

Shared naming conventions allow teams to collaborate efficiently.

What changed

Renames the interface from lowercase result to PascalCase Result, which matches the required naming convention regex ^[A-Z][a-zA-Z0-9]*$. This directly fixes the code smell where the interface name result did not follow the standard naming convention for interfaces/classes.

typescript:S4138 - Expected a `for-of` loop instead of a `for` loop with this simple iteration. • MINOR • View issue

Location: frontend/src/app/oauth/oauth.component.ts:57

Why is this an issue?

for...of statements are used to iterate over the values of an iterable object. Iterables are objects implementing the @@iterator method, which returns an object conforming to the iterator protocol. JavaScript provides many built-in iterables that can and should be used with this looping statement.

What changed

This hunk replaces a traditional for loop (for (let i = 0; i < splitted.length; i++)) with a for...of loop (for (const item of splitted)), and updates the loop body to use the iteration variable item instead of the indexed access splitted[i]. This directly addresses the code smell where a for...of loop should be used instead of a for loop with simple iteration over an iterable array.

SonarQube Remediation Agent could not fix the CI failures.

Task: d408346d-fe37-423d-9f96-037796d082c6
Branch: remediate-master-20260525-010120-f1db793f
Attempt: 1 (of 3)

CI failures escalated for manual fix.
Escalation Reason: The failure is caused by a deprecated GitHub Actions dependency (actions/upload-artifact v3) in the CI workflow files. This is not related to the code changes in the diff and cannot be fixed by patching application source code. The workflow YAML files need to be updated to use actions/upload-artifact@v4, but this is a CI infrastructure/dependency issue outside the scope of the code changes being tested. The same failure would occur on any branch using the deprecated action version.
