port_map: the suggestion provider's budget, newest request and 1000 cap

Three rows in `rest-017.tsv` describe the state of the code before
`ServerCommandSuggestionsProvider` landed in `lan_actions.rs`:

* `tick` is not "no per-tick budget": `guest_try_suggestions` spends a budget
  that the per-guest server tick refills (`play.suggestion_budget = true`
  next to the chat and command throttler decay, then one answer);
* `limitSuggestionCount` is no longer missing: `guest_suggestions` cuts the
  list to its first 1000 suggestions and keeps the range;
* `request` coalesces as `lastRequest` does: the newest command text replaces
  the one not answered yet (`play.suggestion = Some(payload)`).
