fix: plugin passing undefined to plugin item on plugin page

- Refactor onInstall to accept the full plugin object instead of just pluginId.
- Prevent duplicate entries in installed list and DOM.
- Fixes issues where plugins installed via search/filter/direct URL would not appear or just appending default in installed list until page reload.
