feat(web): add icons/emoji to selectors, sync bot enable status and plugin list in sidebar

- Bot adapter selector: show adapter icon in trigger and dropdown items
- Knowledge engine selector: show plugin icon derived from plugin_id
- Pipeline binding selector: show pipeline emoji in trigger and dropdown items
- Knowledge base selectors (single/multi): show KB emoji in all views
- Sidebar bot entries: show green/gray status dot on adapter icon for enable/disable state
- Sidebar plugin list: sync after install/uninstall from all entry points (PluginInstalledComponent, plugins page, marketplace page)
- Pipeline form: add cursor-pointer to left-side tab list buttons
- Clean up unused onBotDeleted prop from BotForm
