Note

Low Risk
Low risk documentation-only change that adds a new troubleshooting page and adjusts sidebar ordering/metadata; no runtime code paths are affected.

Overview
Adds a new Smart Accounts Kit troubleshooting page for allowance-exceeded when redeeming delegations, including guidance for spending-limit exhaustion and delegation-hash collisions (with a salt example).

Updates the troubleshooting sidebar to include the new page and reorders entries, and adds toc_max_heading_level: 2 frontmatter to several existing troubleshooting docs for consistent navigation.
