feat: add API Key Manager button, fix overflow, update branding

Changes:
1. Fixed MULTIX overflow issue - added max-h-full and overflow-hidden to prevent content from pushing interface out of frame

2. Added API Key Manager button in header:
   - Key icon with emerald hover effect
   - Opens modal with provider list (NomadArch Free, Ollama Cloud, OpenAI, Anthropic, OpenRouter)
   - Shows provider status and configuration

3. Updated branding:
   - Window title: 'NomadArch 1.0'
   - Loading screen: 'NomadArch 1.0 - A fork of OpenCode'
   - Updated page titles

4. Added Settings and Key icons to imports
