AAP-69248: WCA OAuth ignores custom Lightspeed URL configuration (#2675)

refactor: simplify getBaseUri by removing WCA fallback logic

Address PR review feedback by fully adopting fail-fast strategy:

1. Remove WCA-specific fallback to WCA_API_ENDPOINT_DEFAULT
- Trust llmProviderSettings.get() to return defaults via provider
factory
   - Add explicit error when apiEndpoint is not configured (defensive)

2. Remove fallback to legacy settings schema
   - Only use llmProviderSettings after migration
   - Check llmProviderSettings initialization first (fail early)

3. Update all tests to match new behavior
   - Tests now expect provider factory defaults
   - Add new tests for empty endpoint error scenarios
   - Remove dependency on old settings structure in mocks

This simplification:
- Removes 15+ lines of redundant code
- Eliminates technical debt from legacy settings
- Provides clearer error messages for misconfiguration
- Follows fail-fast principle for better debugging

All 1544 tests passing, lint checks pass.
