Simplify auth modes to Anthropic and Bedrock, fix Windows taskbar icon

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.

 Each project can independently use one of:
 
-- **`/login`** (OAuth): User runs `claude login` inside the terminal. Token persisted in the config volume.
-- **API Key**: Stored in the OS keychain, injected as `ANTHROPIC_API_KEY` env var.
+- **Anthropic** (OAuth): User runs `claude login` inside the terminal on first use. Token persisted in the config volume across restarts and resets.
 - **AWS Bedrock**: Per-project AWS credentials (static keys, profile, or bearer token).
