Improved Configuration and YAML Management (#2966)
# Description of Changes

**What was changed:**
- **Configuration Updates:**  
Replaced all calls to `GeneralUtils.saveKeyToConfig` with the new
`GeneralUtils.saveKeyToSettings` method across multiple classes (e.g.,
`LicenseKeyChecker`, `InitialSetup`, `SettingsController`, etc.). This
update ensures consistent management of configuration settings.
  
- **File Path and Exception Handling:**  
Updated file path handling in `SPDFApplication` by creating `Path`
objects from string paths and logging these paths for clarity. Also
refined exception handling by catching more specific exceptions (e.g.,
using `IOException` instead of a generic `Exception`).

- **Analytics Flag and Rate Limiting:**  
Changed the analytics flag in the application properties from a `String`
to a `Boolean`, and updated related logic in `AppConfig` and
`PostHogService`. The rate-limiting property retrieval in `AppConfig`
was also refined for clarity.

- **YAML Configuration Management:**  
Replaced the previous manual, line-based YAML merging logic in
`ConfigInitializer` with a new `YamlHelper` class. This helper leverages
the SnakeYAML engine to load, update, and save YAML configurations more
robustly while preserving comments and formatting.

**Why the change was made:**
- **Improved Maintainability:**  
Consolidating configuration update logic into a single utility method
(`saveKeyToSettings`) reduces code duplication and simplifies future
maintenance.
  
- **Enhanced Robustness:**  
The new `YamlHelper` class ensures that configuration files are merged
accurately and safely, minimizing risks of data loss or format
corruption.
  
- **Better Type Safety and Exception Handling:**  
Switching the analytics flag to a Boolean and refining exception
handling improves code robustness and debugging efficiency.
  
- **Clarity and Consistency:**  
Standardizing file path handling and logging practices enhances code
readability across the project.

**Challenges encountered:**
- **YAML Merging Complexity:**  
Integrating the new `YamlHelper` required careful handling to preserve
existing settings, comments, and formatting during merges.
  
- **Type Conversion and Backward Compatibility:**  
Updating the analytics flag from a string to a Boolean required
extensive testing to ensure backward compatibility and proper
functionality.
  
- **Exception Granularity:**  
Refactoring exception handling from a generic to a more specific
approach involved a detailed review to cover all edge cases.

Closes #<issue_number>
