chore: upgrade api7 and gateway to v3.10.2

[jarvis9443]

Release chart bump for API7 EE 3.10.2.

Version bumps

• charts/api7: chart version 3.10.0 → 3.10.1, appVersion → 3.10.2; image tags (integrated dashboard, dp-manager, file-server, developer-portal) → v3.10.2
• charts/gateway: chart version 3.10.1 → 3.10.2, appVersion → 3.10.2; image tag → 3.10.2

Chart version follows the per-line counter (decoupled from the app patch): the api7 and gateway charts advance independently on the 3.10 line.

Structural sync

• charts/gateway: support per-port PROXY protocol on stream_proxy.tcp entries — each entry can now set proxy_protocol (accept) and proxy_protocol_to_upstream (send), overriding the global apisix.proxyProtocol.enableTcpPP* defaults. Mirrors the gateway 3.10.2 config-default change.

READMEs regenerated with make helm-docs.

Summary by CodeRabbit

• New Features

  • Added support for per-TCP-entry proxy protocol settings in gateway stream configuration, allowing more flexible TCP upstream behavior.

• Updates

  • Bumped chart and application versions for API7 and Gateway.
  • Updated default container image tags to the latest release across chart values.

• Documentation

  • Refreshed Helm chart README files to match the new versions and default image tags.

📝 Walkthrough

Walkthrough

Bumps the api7 Helm chart to version 3.10.1 (appVersion 3.10.2) and the gateway chart to version 3.10.2. Updates all component image tags to v3.10.2. Adds conditional proxy_protocol and proxy_protocol_to_upstream fields to the gateway ConfigMap's stream_proxy.tcp rendering for per-port PROXY protocol overrides.
