refactor(examples): reorganize examples into logical sections

Renumber all examples to group by feature area, with each section starting at multiples of 10:

- 01-09: Authentication
- 10-19: Transcription (Listen)
- 20-29: Text-to-Speech (Speak) - including new TextBuilder streaming example
- 30-39: Voice Agent
- 40-49: Text Intelligence (Read)
- 50-59: Management API
- 60-69: On-Premises
- 70-79: Configuration & Advanced

This makes the examples easier to navigate and leaves room for future additions in each section.
