Subject: [PATCH] fix(ui): enable custom parameters in user settings and admin
 model settings (#25200)

Add missing custom={true} prop to AdvancedParams in General.svelte and
ModelSettingsModal.svelte so the 'Add Custom Parameter' option appears
consistently across all advanced parameter surfaces.

Also forward custom_params in the General.svelte save handler so custom
parameters are persisted instead of silently dropped on save.
