feat(p2p): Auto-create mesh repository without modal parameters

Add autoCreateMeshRepo() function that automatically:
- Generates repo name from hostname: secubox-mesh-{hostname}
- Detects local Gitea server (gitea.local, git.local, etc.)
- Only prompts for access token on first use (one-time setup)
- Creates private repository with README
- Pushes initial mesh state immediately

Replace manual "➕ Create" button with "🚀 Auto Setup" for seamless
mesh repository initialization.
