* feat(catalog): introduce defaultTab to usePluginDetailsTabs hook

* feat(catalog): use defaultTab as fallback tab for PluginDetails

* chore(catalog): remove hardcoded page query param in list items

* refactor(catalog): prefer let over react ref when setting default tab in PluginDetails

* refactor(catalog): pass pageId to plugin details body rather than duplicate logic

* test(catalog): remove query param from List item test hrefs

* test(catalog): introduce a test for default app config page for installed app plugins
