PostgreSQL icon has rendering artifact

The PostgreSQL elephant icon in the UI has a small blue triangle artifact visible on the lower right part of the elephant head.

This is caused by improper SVG path closure in the original icon definition.

---

Acceptance Criteria

• The blue triangle rendering artifact on the PostgreSQL elephant icon is eliminated
• The SVG path is properly closed with correct coordinates so no stray triangles appear at any zoom level or screen resolution
• The icon renders identically across Chrome, Firefox, and Safari
• The corrected icon matches the official PostgreSQL elephant design without visual anomalies

Definition of Done

• SVG file updated with corrected path data and proper path closure
• Visual comparison confirms the artifact is gone at 1x, 2x, and 3x display densities
• No regression in icon rendering on the main UI pages where the elephant icon appears
• Change deployed and verified in staging
