Rentiva v4.51.0 — Vendor Management Faz B: Vendors, Commission & Settings React SPA

Vendor Management completes its React SPA migration with Faz B: the Vendors, Commission, and Settings tabs are now fully client-side. Seven new REST endpoints, three new React components, and an N+1 query fix for vendor listing.

What Changed

Vendors Tab — VendorTable Component

The Vendors tab is now a live React table powered by GET /wp-json/mhm-rentiva/v1/admin/vendors. Features:

• Paginated vendor list with vehicle count per vendor (single GROUP BY query — no N+1)
• Suspend / Unsuspend actions via POST /admin/vendors/{id}/suspend and POST /admin/vendors/{id}/unsuspend
• Real-time status badges and inline feedback without page reload

Commission Tab — CommissionTab Component

The Commission tab reads and writes the global commission rate via two new REST routes:

• GET /admin/commission — fetch current rate
• POST /admin/commission — update rate with validation

The PHP render function has been removed; the tab is entirely SPA-driven.

Settings Tab — SettingsTab Component

Vendor Management settings (enable/disable vendor marketplace, terms URL, approval mode) are now managed through:

• GET /admin/vendor-settings — fetch all settings
• POST /admin/vendor-settings — persist changes

REST Endpoints Added (7 total)

Method	Route	Purpose
GET	/admin/vendors	Paginated vendor list
POST	/admin/vendors/{id}/suspend	Suspend a vendor
POST	/admin/vendors/{id}/unsuspend	Unsuspend a vendor
GET	/admin/commission	Get commission rate
POST	/admin/commission	Set commission rate
GET	/admin/vendor-settings	Get vendor settings
POST	/admin/vendor-settings	Update vendor settings

Performance

Vendor list previously issued one COUNT(*) query per vendor to get vehicle counts. This release replaces it with a single GROUP BY aggregation — O(n) → O(1) queries regardless of vendor count.

Test Coverage

19 new PHPUnit tests covering all 7 REST endpoints and their permission, validation, and response contracts.
