perf(fields): create index for instance domain query (#9146) # Which Problems Are Solved get instance by domain cannot provide an instance id because it is not known at that time. This causes a full table scan on the fields table because current indexes always include the `instance_id` column. # How the Problems Are Solved Added a specific index for this query. # Additional Context If a system has many fields and there is no cache hit for the given domain this query can heaviuly influence database CPU usage, the newly added resolves this problem. 2025-01-07 17:06:33 +01:00			`CREATE INDEX CONCURRENTLY IF NOT EXISTS fields_instance_domains_idx`
