Include project and local settings in endpoint classification.

The probe loads stateDir/.claude/settings.json and settings.local.json, but readClaudeSettingsEnv passes undefined instead of its cwd to claudeSettingsPaths. A project or local ANTHROPIC_BASE_URL can therefore make the probe query another endpoint while customApiEndpoint remains false. The status function can then publish that endpoint's usage windows instead of marking them unsupported.

Review comment at @apps/server/src/provider/ClaudeProvider.ts around lines 612 -
622:
Update readClaudeSettingsEnv to pass its cwd to claudeSettingsPaths so project
and local settings are included when resolving ANTHROPIC_BASE_URL; preserve the
existing customApiEndpoint classification and ensure it reflects the endpoint
the probe will query.

After applying the fix, consider running `coderabbit review --agent` for local
review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr
