Humansecurity RTD Provider: migrate to TypeScript and optimize token handling (#6579)

* Humansecurity RTD Provider: migrate to TypeScript and optimize token handling

* - Migrated to TypeScript
- Removed hardcoded token injection into ortb2Fragments and delegate to the HUMAN implementation, enabling management of which bidders receive tokens and enhancing monitoring and control of latency and performance
- Introduce a cached implementation reference via getImpl()
- Add module version query parameter when loading the implementation script
- Wire onAuctionInitEvent so the implementation can collect QoS, telemetry and statistics per auction

* Fix markdownlint errors in humansecurityRtdProvider docs.

Add language tags to fenced code blocks and normalize the parameters table spacing for MD060.
