Enforcer usage patterns (reads vs writes)

[mariajgrimaldi]

Description

The sync enforcer is currently used for both read operations (permission checks) and write operations (policy changes). This may introduce unnecessary overhead during high-volume reads, but we do not have a clear separation between the two paths.

This issue tracks:

• Reviewing where and how the enforcer is used in read paths and write paths.
• Determining whether separating these paths would improve performance or reduce overhead. This is only a theory, we'd have to go deep into casbin to understand whether this would actually have an impact.
