refactor: aiservice deep dive — LLM client, dedup, async, cleanup (#2482)

Browse source 
## Summary

Comprehensive refactoring of the aiservice Django backend focusing on
code quality, deduplication, and correctness:

- **LLM client extraction**: Extract `LLMClient` class with lazy client
init, centralized error handling, and event loop detection
- **Centralize retry logic**: `@stamina.retry` on
`call_anthropic`/`call_openai` for transient errors (rate limits,
timeouts, 500s), removing scattered retry decorators from testgen files
- **Deduplicate helpers**: Consolidate `extract_code_and_explanation`
into shared `context_helpers.py`, unify `normalize_*_code` into
`normalize_c_style_code`
- **Eliminate double DB queries**: Auth middleware `afirst()` then
`aupdate()` by PK, middleware caches org/subscription
- **Parallelize Java optimizer**: Use `asyncio.TaskGroup` for
independent LLM calls
- **Lazy logging**: Convert all f-string logging to lazy `%s` formatting
across 11 files
- **Cleanup**: Remove unused `PipelineError`/`ValidationError`, fix
`seach_and_replace.py` typo, replace `print()` with `logging.debug()` in
middleware
- **Sentry**: Reduce sampling 1.0 → 0.1/0.01, fix auth `settings.DEBUG`
check, sanitize ranker errors

## Test plan

- [x] All existing pytest tests pass (`uv run pytest`)
- [x] Ruff lint/format clean
- [x] No behavioral changes — pure refactoring
