Replace the three auth modes (Login, API Key, Bedrock) with two
(Anthropic, Bedrock). The Anthropic mode uses OAuth via `claude login`
inside the terminal, which generates and stores its own API key in the
persistent config volume. The separate API Key mode is removed because
Claude Code now requires interactive approval of externally-provided
keys, making the injected ANTHROPIC_API_KEY approach unreliable.
Old projects stored as "login" or "api_key" are automatically migrated
to "anthropic" via serde aliases.
Also fix the Windows taskbar icon showing as a black square by loading
icon.png instead of icon.ico for the runtime window icon.

The sidebar config panel content was overflowing its container width,
causing project names and directory paths to be clipped. Added min-w-0
and overflow-hidden to flex containers, and restructured folder path
config rows to stack vertically instead of cramming into one line.
The Windows taskbar was showing a black square because no default window
icon was set at runtime. Added default_window_icon() call in the Tauri
builder using the app's icon.png.
Also adds vitest test infrastructure with tests verifying both fixes.
