fix(config): handle undefined state in config selectors

Fixes #6052

Add null-safety checks to all 15 config selectors to handle
undefined state during app initialization. Prevents crash when
selector-based effects fire before loadAllData completes.

Changes:
- Add nullish coalescing operator to all selectors
- Return DEFAULT_GLOBAL_CONFIG values when state is undefined
- Add 26 unit tests for undefined state handling

All tests pass (41/41). No breaking changes to API or behavior.
