docs: Kyma endpoint table and Runs on Kyma line

[sonpiaz]

Summary

• Document Kyma capability aliases with resolved model ids, Kyma endpoints, and a Runs on Kyma API line at the end of Setup.
• Aliases come from the scripts; resolved models come from bin/models alias expectations.

Evidence

model id	file:line in code	model page HTTP
alias transcribe → whisper-v3-turbo	bin/transcribe:296 (alias); bin/models:124 (resolved id)	200
alias audio-understand → gemini-3-flash-audio	bin/audio-q:134 (alias); bin/models:124 (resolved id)	200

Test plan

• Confirm model links return 200
• Confirm no em-dash on added lines
• README-only diff
