fix: instance detail crash + add play/stop/redeploy/remove actions

Fixes:
1. useFetch: add credentials:'same-origin' — cookie wasn't being sent
   with API calls, causing 401 → React error boundary → 'Etwas ist schiefgelaufen'
2. Instance detail Sheet now loads correctly (cookie sent with request)

New instance actions (UI + API):
- Redeploy: triggers Dokploy application.redeploy (rebuilds from latest commit)
- Stop: triggers Dokploy application.stop (pauses container)
- Start: triggers Dokploy application.start (resumes container)
- Remove: existing delete (SlideCommit confirmation)

Dokploy deploy fix:
- deployApplication now calls markRunning before deploy
- This ensures Dokploy creates a deployment job

ActionsRow redesigned:
- demo_active/active: [Redeploy] [Stop] [Demo +7d] [Remove]
- grace: [Start] [Remove]
- failed: [Retry] [Remove]
- provisioning/deleting/deleted: no actions
