Fix #28: redirect off /provisioning when setup_complete event arrives

[obaid]

Summary

The provisioning page polls every 3s with usePoll({ only: ['server'] }) to detect server.status === 'running' and navigate the user to /agents. Two failure modes leave the user stuck at ~80% even when the server is actually ready:

1. Poll cycle fails silently (network blip / Inertia partial-reload error) — page never gets the updated status.
2. Status column lags the events — the script's setup_complete and gateway_restarted callbacks fire before the status column transitions to running, so for a few seconds the prop says configuring while the server is already up.

Fixes #28.

Changes

• resources/js/pages/settings/teams/provisioning.tsx: derive a new isReadyByEvents flag from the events array — events.some(e => e.event === 'setup_complete' || e.event === 'gateway_restarted'). Either event landing is a strong signal the server is ready. The effect that calls router.visit('/agents') now fires on isRunning || isReadyByEvents, so we hand off as soon as either path signals completion. usePoll's autoStart is also gated on the combined flag so we don't keep hammering after a successful handoff.
• app/Http/Controllers/Settings/TeamController.php: add gateway_restarted to the event-type whitelist so the frontend can see it (it was being filtered out by the whereIn clause).

Tests

• New feature test in tests/Feature/Teams/ServerProvisioningPageTest.php: provisioning page exposes setup_complete + gateway_restarted events so the client can redirect even if status lags (issue #28). Creates a server in provisioning status with the two events attached, asserts both are present in the page payload.
• All existing Teams + Api tests still pass (116 passed, 4 skipped).

Pint: clean. Frontend rebuilt (npm run build).

Live E2E status

⚠️ Live E2E not run on this branch — Expose tunnel was too flaky during PR creation (plane wifi). Recommended manual verification on stable internet:

1. Sign up fresh, create a team on DO
2. Watch the provisioning page through to completion
3. Confirm the page auto-redirects to /agents within a few seconds of setup_complete landing in the activity feed (not stuck at 79% / 90%)
4. Repeat with DevTools throttled to "Slow 3G" — should still redirect (the event-based fallback handles cases where polling lags)

Test plan

• CI green
• Live E2E on stable internet — page auto-redirects to /agents
• Throttled-network E2E — page still redirects when polling is slow
