Refactor examples: reorganize and update scripts for managing Telegram services

- Removed outdated example scripts for managing anonymous numbers, making raw API calls, fetching wallet info, and various giveaways.
- Introduced new scripts for searching gifts, numbers, and usernames in the Fragment marketplace.
- Added examples for recharging Telegram Ads accounts and managing user balances with TON.
- Updated example scripts to improve clarity and maintainability, ensuring they align with the latest API changes.

+Example: send a raw request to any Fragment API method.
+
+Use client.call() when you need to access a method that is not yet
+wrapped by the library, or to inspect raw API responses directly.
+
+page_url is optional — only set it when the target method belongs to a
+specific Fragment page (Fragment derives the API hash per page).
+Defaults to the Fragment base URL.
