rka-oai 8aae858958 Add auto-compaction fallback token-budget settings (#33243)
## What changed

- Add `auto_compact_fallback_prompt` and
  `auto_compact_fallback_buffer_tokens` to `features.token_budget` and the
  generated configuration schema.
- Trim empty fallback prompts, limit prompts to 2,000 bytes, require a buffer
  when a prompt is configured, and reject non-positive buffer values.
- Preserve the new settings when locking resolved session configuration.

## Testing

- Cover config resolution and validation for overlong prompts, missing
  buffers, and non-positive buffers.
- Extend the configuration-lock test to cover both settings.
