fix: add missing auth env variables

[cristipufu]

Pull request overview

This PR updates the dev server authentication flow to persist additional UiPath identifiers (tenant + organization IDs) into both os.environ and the local .env, aligning runtime configuration with the resolved auth context.

Changes:

• Add UIPATH_TENANT_ID and UIPATH_ORGANIZATION_ID to the finalized auth environment (process env + .env file).
• Clear the newly added env vars on logout.
• Bump project version to 0.0.67 (and update uv.lock accordingly).
