chore: apply Rector refactors to ConfigTest

[Copilot]

This PR applies the repository’s Rector rules and commits the resulting updates. The changes are scoped to ConfigTest and align PHPUnit assertions with current Rector/Nextcloud rule expectations.

• Scope

  • Updated /home/runner/work/nextcloud_sentry/nextcloud_sentry/tests/Unit/ConfigTest.php only.
  • No production code or runtime behavior changes.

• Rector-driven PHPUnit updates

  • Marked the test class as final.
  • Replaced static assertions (self::assert*) with instance assertions ($this->assert*).
  • Replaced float assertSame(...) assertions with assertEqualsWithDelta(..., PHP_FLOAT_EPSILON) for numeric precision-safe checks.

• Representative diff

  -class ConfigTest extends TestCase {
  +final class ConfigTest extends TestCase {
  
  -self::assertSame(0.5, $result);
  +$this->assertEqualsWithDelta(0.5, $result, PHP_FLOAT_EPSILON);

Walkthrough

The ConfigTest class is refactored to adopt instance-level PHPUnit assertions. The final keyword is added to the class declaration. All static assertion calls (self::assert*) are converted to instance method calls ($this->assert*). Additionally, floating-point value assertions are changed from strict equality (assertSame) to tolerance-based comparisons (assertEqualsWithDelta with PHP_FLOAT_EPSILON), affecting sampling-rate and profile-sampling-rate tests while maintaining type assertions.

Poem

🐰 With final grace and instance calls,
From self to \$this the refactor sprawls,
Float precision—epsilon's touch—
Makes testing fairer, oh so much!
A rabbit's hop toward cleaner walls! ✨
