<issue_title>Update setSpinnerColor to return $this for method chaining</issue_title>
<issue_description>## Suggestion

To support method chaining and maintain consistency with other methods in the trait (like loadingIndicator), update the setSpinnerColor method so that it returns $this instead of void.

Current Implementation

query-builder/src/Support/Concerns/WithIndicator.php

Lines 32 to 35 in ab245a7

	$this->spinnerColor = $color;
	}
	public function showOverlay(): bool

The method currently returns void, which breaks method chaining:

public function setSpinnerColor($color): void
{
    $this->spinnerColor = $color;
}

Proposed Change

public function setSpinnerColor($color): static
{
    $this->spinnerColor = $color;
    return $this;
}

Benefits

• Enables fluent API pattern for method chaining
• Maintains consistency with the loadingIndicator() method in the same trait
• Does not break existing code (backward compatible)
• Allows for more concise configuration:

  $builder->setSpinnerColor('text-green-500')
          ->loadingIndicator(true);
  ```</issue_description>
