Original Pull Request: https://github.com/netbirdio/netbird/pull/4056

State: closed
Merged: No

Describe your changes

This PR removes shared locking on read operations to avoid deadlocks and adds a GORM index on the UserID field in the Peer model.

Swapped all store.LockingStrengthShare usages for store.LockingStrengthNone on read calls.
Added a GORM index tag to Peer.UserID for improved lookup performance.

We've seen a few deadlock reports for queries with and without transactions that only needed to read data. This Pr removes the locking for share usage and left only the locking for update in use.
