[style](trx-frontend-http): make bookmark decoders selectable; gate add on control role

Replace the free-text decoder input with FT8/WSPR checkboxes so users
cannot enter arbitrary decoder strings. Hide the "+ Add Bookmark" button
by default and show it only when the authenticated role is `control`
(or auth is disabled), matching the server-side write-endpoint guard.
