Rename the remaining "Kubernetes Access Gateway" references to "Gateway"

[Copilot]

Pull request overview

This PR completes the repository-wide rename of remaining “Kubernetes Access Gateway” references to the shorter “Gateway”, aligning docs, Helm chart metadata, dashboards, CLI help text, and GitHub automation with the new naming from Issue #253.

Changes:

• Updated README and ancillary docs/templates to point at the renamed Twingate/gateway repository and “Gateway” terminology.
• Renamed “Kubernetes Access Gateway” strings inside Helm chart values/schema and Grafana dashboard JSON + test snapshots.
• Updated automation/config references (vulnerability monitoring workflow, Codecov config) to use the new “gateway” naming.
