If sanitization of default person properties fails, log a warning and skip
setting the properties instead of silently falling back to empty dictionary.

Apply SwiftFormat fixes to remove trailing spaces, consecutive spaces,
and redundant internal access control.

Document the new default properties support for feature flag evaluation
that eliminates race conditions during SDK initialization.

Remove redundant waitFlagsRequest calls before getFlagsRequest calls,
since getFlagsRequest internally waits for the expectation. This fixes
the "expectations can only be waited on once" error in CI.

System-provided properties don't need sanitization as they are already
safe for JSON serialization.

App updates only occur on fresh launches, making this refresh redundant
since setDefaultPersonProperties is already called during SDK initialization.

Read locale directly from Locale.current instead of calling expensive
dynamicContext() method that computes many unnecessary values.

Method is no longer needed after removing Application Updated refresh logic.

Remove extra blank lines to satisfy SwiftFormat linter.

- Add setGroupPropertiesForFlagsIfNeeded helper method
- Automatically set person properties for flags in capture() method when userProperties or userPropertiesSetOnce are provided
- Automatically set group properties for flags in group() method when groupProperties are provided

This ensures feature flag evaluation has access to the latest properties without requiring manual calls to setPersonPropertiesForFlags or setGroupPropertiesForFlags.

- Test that capture() with userProperties automatically sets person properties for flags
- Test that group() with groupProperties automatically sets group properties for flags

These tests verify that feature flag evaluation has access to properties passed to capture() and group() methods without requiring manual calls to the property setter methods.

This improves code organization by:
- Making groupIdentify fully responsible for all group-related operations
- Matching the pattern used in identify() for consistency
- Ensuring flag properties are set even if groupIdentify is called from other places in the future
- Simplifying the public group() method to only handle validation and delegation

- Add hasPersonProcessing() check to setPersonPropertiesForFlags
- Add hasPersonProcessing() check to setGroupPropertiesForFlags
- Add hasPersonProcessing() check to resetPersonPropertiesForFlags
- Add hasPersonProcessing() check to resetGroupPropertiesForFlags

This ensures consistency with internal helper methods and prevents setting properties for feature flags when person processing is disabled (e.g., when personProfiles is set to 'never').

- Add optional reloadFeatureFlags parameter to setGroupPropertiesForFlags for consistency with setPersonPropertiesForFlags
- Maintain backward compatibility with a convenience overload that defaults to true
- Update documentation to explain both usage patterns

This allows users to batch multiple group property updates before reloading flags, improving performance when setting properties for multiple groups.

- Remove 'test' prefix from @test methods (Swift Testing convention)
- Remove trailing spaces from all lines

These changes comply with the project's SwiftFormat and SwiftLint rules.

Clear personPropertiesForFlags and groupPropertiesForFlags when resetting
the SDK storage. This ensures that cached feature flag properties are
properly cleaned up during reset operations.
