plugin disable system: kernel→SDK PluginManager + WebUI/CLI

- New disabled_plugins table (name, disabled_at, disabled_by)
- SDK.PluginManager interface: DisablePlugin/EnablePlugin/ListDisabledPlugins
- Registry implements PluginManager, wired into PluginSDK
- WebUI: POST /api/v1/plugins/<name>/disable|enable + plugins page with toggle
- Disabling webui shows confirmation dialog
- CLI: /plugin disable <name> / /plugin enable <name>
- pluginmgr removePlugin sync-cleanup from disabled_plugins table
