feat: Add Authentik recovery and invitation flows

This commit adds password recovery and user invitation flows for Authentik,
enabling users to reset passwords via email and admins to invite users.

Features Added:
- Recovery flow: Users can request password reset emails
- Invitation flow: Admins can send user invitation emails
- Python scripts use Authentik API (no hardcoded credentials)
- Flows task automatically verifies/creates flows on deployment

Changes:
- authentik/files/create_recovery_flow.py: Recovery flow script
- authentik/files/create_invitation_flow.py: Invitation flow script
- authentik/tasks/flows.yml: Flow configuration task
- authentik/tasks/main.yml: Include flows task

This ensures:
✓ Password recovery emails work automatically
✓ User invitations work automatically
✓ Flows are configured on every deployment
✓ No hardcoded credentials (uses bootstrap token)
