fix(acp): increase default prompt timeout 60s to 120s for BYO-LLM proxies (#3243)

Closes #3243

- Increase DEFAULT_REQUEST_TIMEOUT_MS from 60s to 120s
- Update config default acpPromptTimeoutMs to 120_000
- Update 8 test files with matching inline Config values
- Add config.test.ts assertion for new default
- Validated by dogfooding gap: CC could not complete within 60s through z.ai proxy
