Replace the structured search filter approach with from_text(), enabling
the full search syntax (is:nc, occupies:background, user:owns, etc.) in
a single text field.
Changes:
- Search form now uses single `q` text param instead of `q[name]`
- Controller uses Item::Search::Query.from_text instead of from_params
- Auto-fit filter applied via .merge(Item.fits(body_id)) in controller
- Added error handling for Item::Search::Error
- Updated pagination param from `q[page]` to `page`
- Removed build_search_filters method (no longer needed)
- Fixed outfit_state_params helper to handle q as string

Reproduce:
1. Add an item with animations, and play them.
2. Remove the item.
3. Add it back.
4. Observe the button shows up in "Paused" state, even though it's playing.
This is because the server-side template wasn't doing anything to try to keep the play/pause button it renders in sync with the current saved state in the cookies, so it was always causing a morph to the pause state. Now we listen to the cookie instead!
I also updated the JS behavior to be a bit more consistent: treat the behavior as defaulting to true, unless it's explicitly set to the string "false".
