[feature/patina-boot] patina_boot: Refactor to trait-based boot orchestration design

[kat-perez]

Description

Refactor patina_boot from a component-based design to a trait-based design per the updated boot orchestration RFC.

Old design: BootOrchestrator and ConsoleDiscovery were standalone Patina #[component]s that each independently implemented boot logic.

New design:

• BootOrchestrator: Plain Rust trait defining the boot flow interface
• BootDispatcher: Single Patina #[component] that installs the BDS architectural protocol and delegates to Box<dyn BootOrchestrator>
• SimpleBootManager: Default trait implementation under impls/, constructed via from_options(BootOptions) or from_config(SimpleBootConfig)

Also adds SimpleBootConfig for platforms with fixed primary/secondary boot topologies, and updates doc references throughout.

• Impacts functionality?
• Impacts security?
• Breaking change?
• Includes tests?
• Includes documentation?

How This Was Tested

• cargo build -p patina_boot
• cargo test -p patina_boot — 39 tests pass (config + helpers)
• cargo clippy -p patina_boot — zero warnings

Integration Instructions

Replace component registration:

// Before:
add.component(BootOrchestrator);

// After:
add.component(BootDispatcher::new(SimpleBootManager::from_options(
    BootOptions::new()
        .with_device(nvme_path())
        .with_hotkey(0x16)
        .with_hotkey_device(usb_path()),
)));

// Or with SimpleBootConfig for fixed primary/secondary:
add.component(BootDispatcher::new(SimpleBootManager::from_config(
    SimpleBootConfig::new(nvme_path(), usb_path())
        .with_hotkey(0x16),
)));

// Or with a custom orchestrator:
add.component(BootDispatcher::new(MyCustomOrchestrator::new()));
