docs: add text-indexed properties table to query language reference

closes #635 (closed)

What does this MR do?

Adds a ### Text-indexed properties section to the Filters section of docs/source/remote/queries/query-language.md, listing every entity and the properties that support token_match, all_tokens, and any_tokens.

Also syncs skills/orbit/references/query_language.md (required by the orbit-skill-docs-sync pre-commit hook).

Why?

The query language reference documented the three token operators but gave no indication of which properties they actually work on. Users had to trial-and-error or dig into the ontology YAML themselves.

The data was extracted directly from config/ontology/nodes/**/*.yaml by scanning for type: "text(tokenizer" skip indexes.

Verification
