refactor(api): update roles REST endpoints to typed TypeBox validateParams

[Harshit2405-2004]

Description

Currently, in \�pps/meteor/app/api/server/v1/roles.ts, the legacy endpoints map custom syntax validation bounds inside the execution block instead of relying on the native REST typings map parameter \�alidateParams.

This PR officially migrates the following endpoints mapped to @rocket.chat/rest-typings\ TypeBox bounds, effectively completing their domain migration to exact the GSoC Replace Old REST API Definition goals:

• 
  oles.addUserToRole`n-
  oles.getUsersInRole`n-
  oles.delete`n-
  oles.removeUserFromRole`n-
  oles.sync`n
  (Also exposed the missing runtime validation interface schema \isRoleSyncProps\ inside
  est-typings)

P2: `roles.getUsersInRole` was likely missed in the TypeBox `validateParams` migration: the validator `isRolesGetUsersInRoleProps` is imported but never assigned to `validateParams`, leaving query params unvalidated and the import unused.</violation>
