Pull request overview

This PR adds a comprehensive guide on applying oracle reports to stVaults, which is an essential operational requirement for vault operations. The guide explains when reports need to be applied, how to apply them using different interfaces (Web UI, CLI, Etherscan), and how to check report freshness.

Changes:

• New documentation guide for applying oracle reports to vaults (applying-report-guide.md)
• Updated references in basic-stvault.md to link to the new reporting guide and reorganized info blocks into inline text
• Adjusted sidebar position of node-operators-identification.md to accommodate the new guide
