Commit Message

Instantiate validators at definition time

  - Store validator instances in ParamsScope/ContractScope and have
    Endpoint#run_validators read them directly
  - Remove ValidatorFactory indirection and eagerly compute validator
    messages/options in constructors
  - Extract Grape::Util::Translation module shared by Exceptions::Base
    and Validators::Base for I18n translate with fallback locale
  - Support Hash messages in translate_message for deferred translation
    with interpolation parameters (e.g. { key: :length, min: 2 })
  - Normalize Grape::Exceptions::Validation params handling and refactor
    validator specs to define routes per example group
  - Drop test-prof dependency and its spec config
