[WV2] Improve pagination with page dropdown

Replace will_paginate's view helpers with a custom prev/next + page
dropdown control.

Layout: [← Prev] [Page <select> of N] [Next →]
- Prev/Next are regular links (work without JS)
- Dropdown wrapped in <auto-submit-form> for JS-enhanced navigation
- "Go" submit button appears when JS is disabled
- Single pagination bar at top of results (removed bottom duplicate)
