feat(Digest): Add RLS at digest generation for Charts and Dashboards

[geido]

SUMMARY

Digest generation for charts and dashboards wasn't considering RLS for users and guest users (via Embedded). This PR includes the RLS in the hash generation for the digest. The digest is included in cache keys and will be updated according to the RLS rules. Previously you could generate a screenshot and any RLS applied later won't be applied to follow-up screenshots as the same cache key was being reused.
