feat: implement preferred port allocation and per-address enable/disable

- Add AvailablePorts::try_alloc() with SSL tracking (BTreeMap<u16, bool>)
- Add DerivedAddressInfo on BindInfo with private_disabled/public_enabled/possible sets
- Add Bindings wrapper with Map impl for patchdb indexed access
- Flatten HostAddress from single-variant enum to struct
- Replace set-gateway-enabled RPC with set-address-enabled
- Remove hostname_info from Host; computed addresses now in BindInfo.addresses.possible
- Compute possible addresses inline in NetServiceData::update()
- Update DB migration, SDK types, frontend, and container-runtime

+### Verifying code changes
+
+When making changes across multiple layers (Rust, SDK, web, container-runtime), verify in this order:
+
+1. **Rust**: `cargo check -p start-os` — verifies core compiles
+2. **TS bindings**: `make ts-bindings` — regenerates TypeScript types from Rust `#[ts(export)]` structs
+   - Runs `./core/build/build-ts.sh` to export ts-rs types to `core/bindings/`
+   - Syncs `core/bindings/` → `sdk/base/lib/osBindings/` via rsync
+   - If you manually edit files in `sdk/base/lib/osBindings/`, you must still rebuild the SDK (step 3)
+3. **SDK bundle**: `cd sdk && make baseDist dist` — compiles SDK source into packages
+   - `baseDist/` is consumed by `/web` (via `@start9labs/start-sdk-base`)
+   - `dist/` is consumed by `/container-runtime` (via `@start9labs/start-sdk`)
+   - Web and container-runtime reference the **built** SDK, not source files
+4. **Web type check**: `cd web && npm run check` — type-checks all Angular projects
+5. **Container runtime type check**: `cd container-runtime && npm run check` — type-checks the runtime
+
+**Important**: Editing `sdk/base/lib/osBindings/*.ts` alone is NOT sufficient — you must rebuild the SDK bundle (step 3) before web/container-runtime can see the changes.
