Refine search page and hero search: dynamic subscript, mat-select paginator, search propagation

- Use subscriptSizing="dynamic" on hero search and search page inputs
- Replace native select with mat-select for items-per-page in search page
- Propagate search text to type pages via ?search= query param
- Remove back button negative margin
