fix(ui): disable chat refresh button during active agent turn

Angfr95 · Angfr95 · commit ec35ffac07f6 · 2026-04-29T23:14:54.000+02:00
The refresh button was only guarded by chatLoading and connected state, allowing clicks during active agent turns. This could stall the run, reset chat state, and wedge the gateway. Add chatSending, chatRunId, and chatStream guards to match the existing busy-state pattern used by the model and thinking selects. Fixes #65522
