chore: bump api7 and gateway chart versions for v3.9.8

[jarvis9443]

Changes

• Bump api7 chart version: 0.17.48 → 0.17.49
• Bump gateway chart version: 0.2.58 → 0.2.59
• Update appVersion to 3.9.8 for both charts
• Update image tags:
  • api7-ee-3-integrated: v3.9.7 → v3.9.8
  • api7-ee-dp-manager: v3.9.7 → v3.9.8
  • api7-ee-developer-portal: v3.9.7 → v3.9.8
  • api7-ee-3-gateway: 3.9.7 → 3.9.8
• Add file-server component (3 new templates: configmap, deployment, service; disabled by default via file_server.enabled: false)
• Add Vault role_type config (dynamic/static) to dashboard, dp_manager, and developer_portal database vault sections
• Regenerated README.md via helm-docs

Test Plan

• helm template renders correctly with default values (file-server disabled)
• helm template --set file_server.enabled=true renders file-server configmap, deployment, and service correctly
• All CP helm changes from v3.9.7→v3.9.8 have been synced (busybox removal, topologySpreadConstraints, nodePort, Vault config from PRs feat: create developer-portal-fe helm chart #266-chore(api7): add max_lifetime and Vault config to dp_manager and developer_portal #273, plus file-server and vault role_type in this PR)

90-93: Avoid defaulting file_server to a mutable dev tag.

tag: "dev" on Line 93 bypasses the deployment fallback to chart appVersion (Line 41 in charts/api7/templates/file-server-deploy.yaml) and makes rollouts non-reproducible when this component is enabled.
