css: Align server tooltip with sidebar for security

Previously, the server tooltip was positioned too far to the right,
leaving a gap that entirely disconnected it from the trusted native
sidebar (breaking the 'Line of Death' security boundary).

This aligns the server tooltip's positioning with other sidebar
tooltips (like Settings and DND) by standardizing the 'left' offset
while ensuring the tooltip arrow explicitly overlaps the trusted
sidebar area. This maintains the visual security boundary while
fixing the visual inconsistency that was reported.

Fixes #1087.
