Add missing CEL variable declarations for tag_search and property in
the filter environment so the documented filter syntax works.
- schema.go: Add tag_search as VirtualAlias for tags, add property
as DynType CEL variable
- parser.go: Convert VirtualAlias==value to InCondition for JSONList
targets, handle property.X selector expressions
- render.go: Generalize hardcoded tag check to support any VirtualAlias
resolving to JSONList
- Add integration tests for tag_search, property, and combined filters
Fixes#5761
