Subject: [PATCH] Fix missing `require` statements for Ruby standard libraries
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`lib/cloudinary/base_api.rb` calls `Time.parse` in
`Response#initialize` and `Base64.urlsafe_encode64` in
`get_authorization_header_value`. `lib/cloudinary/search.rb` calls
`Base64.urlsafe_encode64` and `JSON.generate` in `Search#to_url`.
`lib/cloudinary/utils.rb` calls `Base64.urlsafe_encode64` in
several places (e.g. signed URL generation). None of these files
require `time` / `base64` / `json` directly.

Historically this worked by accident because the test suite's
`spec_helper` pre-requires `active_storage/test_helper`, `nokogiri`,
and friends, which transitively load those stdlibs before
`cloudinary` is loaded. In a plain Ruby process — for example on
Ruby 4.0 — `require "cloudinary"` succeeds but the affected paths
fail:

    NoMethodError: undefined method 'parse' for class Time
      …/cloudinary/base_api.rb:30:in 'Cloudinary::BaseApi::Response#initialize'

    NameError: uninitialized constant Cloudinary::Utils::Base64
      …/cloudinary/utils.rb:620:in 'Cloudinary::Utils.cloudinary_url'

    NameError: uninitialized constant Cloudinary::Search::Base64
      …/cloudinary/search.rb:140:in 'Cloudinary::Search#to_url'

This follows the same pattern as e2fb1138 ("Add missing
`require 'net/http'`"), adding the explicit stdlib `require` lines
that each affected file needs.
