Note

Low Risk
Low risk documentation-only change that adds a new reference page and links it in the sidebar; no runtime or API behavior is modified.

Overview
Adds a new reference/advanced-permissions/rules documentation page describing supported ERC-7715 rule types (Expiry, Redeemer, Payee) with parameters and TypeScript examples.

Updates gator-sidebar.js to include the new Rules page under the Advanced Permissions (ERC-7715) Reference section.
