[BUG] SearchParameter Role.name must be token not string

[ruscoder]

We have some queries something like get /Patient?_has:Role:patient:name=patient and it works pretty slow when Role.name is string search param type. Currently solved the issue by manually creating new name-token search param with proper type, but it's very inconvinient. I believe that such small change is really easy to do in the core.

get /Role?name=patient

  - >-
    SELECT "role".* FROM "role" WHERE
    aidbox_text_search(knife_extract_text("role".resource,
    $JSON$[["name"]]$JSON$)) ilike unaccent(?) LIMIT ? OFFSET ? 
  - '% test%'
  - 100
