Ccip rate limit management

[gfletcher-cll]

This pull request introduces a comprehensive new "Rate Limit Management" documentation section for CCIP, aimed at operators and administrators managing cross-chain token transfer limits. The changes add a new sidebar folder with multiple detailed pages covering the conceptual model, permissions, inspection, configuration, emergency actions, and operational scenarios for CCIP rate limits. The documentation is structured to guide users through understanding, configuring, and safely managing rate limits, with special attention to operational risk and best practices.

New Documentation Section: Rate Limit Management

Sidebar and Navigation

• Added a new "Rate Limit Management" section to the CCIP sidebar, including pages for overview, conceptual explanation, permissions, inspection, decimals, updates, emergency actions, common scenarios, and multisig execution.

Concepts and Operations

• Added an overview page describing the purpose, scope, and risk considerations of CCIP rate limits, emphasizing their operator-level impact and the need for careful management.
• Added a conceptual page explaining how rate limits work as capacity buckets, the difference between inbound and outbound limits, and the significance of each configuration parameter.
• Added a permissions and prerequisites page detailing the required rateLimitAdmin role, how it is granted, and the operational responsibilities of administrators.
• Added a page on inspecting current rate limit configurations, including contract methods, required information (token pool address, chain selector), and interpreting on-chain state.

Practical Guidance and Incident Response

• Added a page on handling emergency actions, outlining how to quickly lock down a lane by setting minimal capacity and refill values, and considerations for restoring normal operation.
• Added a scenarios page with worked examples for common token types (18- and 6-decimal tokens), pausing lanes, and fully removing rate limits, including how to recalculate values for each use case.
• Added a page on executing rate limit changes with a multisig, including transaction structure, verification steps, and the ABI for the relevant contract function.
