[nobump] Unlocked Restrictions: screenshots, copy-forwarding, protected-chat lock

Replaces the pluginBase sample with the plugin:
- remove FLAG_SECURE (FlagSecureReason + Window.setFlags) for screenshots
- unlock forward/copy/save UI in protected chats and re-send protected
  messages as copies from the user's account (media re-uploaded, albums
  regrouped, bot-only parts dropped)
- red lock before protected chats' names in the chat list, header and info
- settings toggles for all three
- verify_bundle.py rewritten for the plugin
- bundle.py enables the git hooks on first run; README documents them
