Normalize path separators in config file names to dots

Normalize path separators in config file names

Adds normalization of path separators (/ and \) to dots (.) when registering package configurations.

Before: $this->mergeConfigFrom($vendorConfig, $configFileName);
After: $this->mergeConfigFrom($vendorConfig, str_replace(['/', '\\'], '.', $configFileName));

This ensures config file names with path separators (e.g., subfolder/config) are properly converted to dot notation (subfolder.config), which is required for Laravel config keys.

Benefits:

• ✅ Supports nested config files (e.g., subfolder/config)
• ✅ Cross-platform compatibility (handles both / and \)
• ✅ Maintains backward compatibility with simple file names

The tests are failing. Could you take a look?

[leolnid]

The failing tests appear unrelated to this PR. Only ProcessConfigs.php was modified for config path normalization, with no changes to Blade components, view registration, or test infrastructure.

Failures:

1. Blade component test: No hint path defined for [__components] - occurs only on CI with prefer-lowest
2. TestCase error: Access to undeclared static property ... $latestResponse - appears to be a testbench compatibility issue with minimum versions

Both errors occur only on CI with prefer-lowest dependencies, suggesting compatibility issues with minimum Laravel/testbench versions or pre-existing conditions. The config normalization changes are isolated and shouldn't affect these areas.

Could someone help investigate if these are dependency version issues or pre-existing problems?
