docs: Update PowerSync recipe with latest content

[stevensJourney]

Overview

This will eventually update the local first recipe for PowerSync. This PR exists here first for internal feedback and discussion.

The recipe was quite outdated.

Work done:

• Removed polyfill installation steps and Flipper network inspector step
• Added Metro config step for inline requires
• Fixed minor inconsistencies in code blocks. Some steps include importing code which is only created much later in the guide.
• Updated hooks to use useQuery instead of the deprecated usePowerSyncQuery
• Removed the need for the expo-crypto package by using built-in uuid() method
• Fixed Typos in table name constants

This was tested by following the guide. It would be nice if a reviewer could double check this on their end.
