Implement UI changes for API Revision Deployment Monitoring

[DakshithaS]

Description:

Improved gateway visibility and deployment status monitoring across environments to help API publishers and administrators track deployments more accurately.

Key Enhancements:

• Admin Portal:
  • Added a new "Gateway Instances" column in the Environment listing.
  • Note: The Gateway Instances icon button is only enabled when the gatewayType is Regular.
  • Clicking the icon opens a dialog showing:
    • Gateway ID
    • Status (ACTIVE/EXPIRED)
    • Last active time

Screenshot – Environment Listing View:
Displays the new Gateway Instances column in the environment table.

Screenshot – Gateway Instances Modal:
Shows gateway instance details, including ID, status, and last active timestamp.

• Publisher Portal:
  • Added a "Deployment Status" column in the revision deployment view.
  • Note: This column appears only when the gateway vendor is WSO2.
  • Displays deployment state across live gateway instances per environment.
  • Tooltip includes:
    • Count of deployed, failed, and total gateways
    • Last updated time
    • Visual progress bar
  • Includes polling (configurable via settings.json) to refresh status periodically.
  • Shows statuses: Successfully Deployed, Partially Deployed, Deployment Failed, Inconsistent

Screenshot – Deployment Status View:
Shows the new Deployment Status column with tooltips and visual indicators for deployment progress.

Benefits:

• Real-time visibility into deployment propagation across nodes.
• Enhanced user experience for both publishers and platform administrators.

Steps to reproduce:

1. Deploy WSO2 API Manager with multiple gateway nodes in a distributed setup.
2. Go to Admin Portal → Environments → Click "Gateway Instances" icon.
3. Go to Publisher Portal → API → Deployments → Observe "Deployment Status" column.
4. Deploy a revision and monitor real-time updates.
