fix(web): open provider settings on the Models tab

[Gigioxx]

Fixes #8521.

Since #8380 every provider opened its editor on the Configuration tab, so set-once plumbing (display name, accent color, env vars, binary path) was the first thing on the Providers page instead of the Models list users actually change.

ProviderInstanceCard now initialises activeTab to "models". The existing visibleTab guard still forces Configuration for unknown drivers that have no Models tab, so nothing changes for custom fork instances.

• vp run typecheck in apps/web
• Targeted lint
• Verified in Chrome at 1536 x 860: default selection and switching providers both land on Models; Configuration stays one click away
• Codex review of the diff: no findings

Note

Low Risk
Single default UI state change with no API, auth, or data-handling impact; unknown-driver fallback behavior is preserved.

Overview
Provider instance editor now opens on the Models tab instead of Configuration, so the Providers page surfaces model visibility/favorites first rather than one-time plumbing (display name, env vars, binary path).

Only the initial activeTab state in ProviderInstanceCard changes from "configuration" to "models". The existing visibleTab rule still pins Configuration when driverOption is missing (unknown/custom fork drivers with no Models tab), so that path is unchanged.

Note

Set default tab to models in ProviderInstanceCard

Changes the initial activeTab state in ProviderInstanceCard.tsx from configuration to models. The Models tab is now shown first when opening provider settings.
