refactor: always preserve marketplace search state in URL

Bug: The logic for isSearchMode is inverted, causing categories with collections to show the search view and categories without collections to incorrectly attempt to show the collections view.
_{Severity: CRITICAL}

Suggested Fix

Restore the correct logic by re-adding the negation operator ! to the expression. The line should be changed back to || (searchMode ?? !PLUGIN_CATEGORY_WITH_COLLECTIONS.has(activePluginType)), which correctly enables search mode only for categories that do not have collections.

Potential issue: The logic determining whether to show the plugin collections view or
the search/list view has been inverted due to the removal of a `!` operator. In the new
code, when a user navigates to a plugin category that has collections (e.g., 'all' or
'tool'), the `isSearchMode` flag is incorrectly set to `true`, forcing the search view
and hiding the collections. Conversely, for categories without collections,
`isSearchMode` becomes `false`, causing the UI to incorrectly attempt to render a
non-existent collections view. This breaks the core navigation and display functionality
of the plugin marketplace.

Bug: The client-side hook uses the tab query parameter, but the server-side hydration logic still expects category. This mismatch breaks server-side rendering state preservation for the marketplace.
_{Severity: HIGH}

Suggested Fix

To resolve the mismatch, update the server-side logic to expect the tab query parameter. In web/app/components/plugins/marketplace/search-params.ts, rename the category key in the marketplaceSearchParamsParsers object to tab to align with the client-side useQueryState('tab', ...) hook.

Potential issue: A mismatch exists between the client-side and server-side query
parameter names for the active plugin category. The client-side `useActivePluginType`
hook was updated to use the URL parameter `?tab=`, but the server-side rendering logic
in `hydration-server.tsx` still expects the parameter to be `?category=`. This
discrepancy breaks server-side rendering (SSR) hydration for the marketplace page. When
a user navigates to a URL with `?tab=...`, the server will fail to read the active tab
state, leading to an incorrect initial page render and loss of state on page reloads.
