Collapse algorithm filters into Algos dropdown

- Replace inline filter buttons in desktop header with a single
  "Algos" dropdown that shows all discovery algorithms in a glass
  menu with checkmark for the active selection and a clear option
- Button label dynamically shows the active algorithm name or
  defaults to "Algos" when no filter is active
- Rename mobile tab bar "Filters" to "Algos" with a gear icon
- Rename bottom sheet title to "Algos" to match
