Pull request overview

Adds support in the Console cluster UX to configure GCP NAT Gateway static egress IPs (enable/disable + count), wiring the settings through both cluster creation flow and existing cluster network settings, alongside updated API client types.

Changes:

• Introduces GCP NAT gateway “static egress IPs” settings UI and serialization to nat_gateway_type payload format.
• Updates cluster network settings to read/write GCP/Scaleway NAT gateway feature shapes (including legacy Scaleway shapes) and handle missing GCP NAT_GATEWAY feature on older clusters.
• Bumps qovery-typescript-axios (and axios) to pick up the new NAT gateway types.

this case is legacy-only (NAT_GATEWAY without STATIC_IP). In the normal flow we merge both into GcpStaticIp, where static_ips_enabled is already represented by the sub-toggle, so changing this fallback toggle to always true would be misleading.
