Kattavat promptit + opettavat tooltipit jokaiselle parametrille

Promptit laajennettu moninkertaisiksi jokaiselle agentille:
- Manageri: RULES + EXAMPLE OUTPUT -formaatti
- Koodari: 8 CRITICAL RULES + NEVER-lista (importit, nimeäminen, Pydantic v2)
- Data: SQLAlchemy-spesifit ohjeet (String(length), connect_args, sessionmaker)
- QA: pytest-testirakenne (5 testitapausta enumeroituna)
- DevOps: 7-kohdan CHECKLIST + LGTM/ISSUE-vastausformaatti
- Tarkkailija: 4-alueen arviointi + RISK-formaatti + SHIP IT/NEEDS WORK

Tooltipit (hover 💡):
- Temperature: milloin matala/korkea, suositukset per rooli
- Max tokens: milloin nostaa/laskea, ~1 token ≈ 4 merkkiä
- Top-K: milloin muuttaa, harvoin tarpeen
- Repetition penalty: miksi liian korkea rikkoo koodin
- System prompt: hyvän promptin rakenne (rooli → säännöt → esimerkit → kiellot)

Prompt-tekstikenttä kasvatettu 4 → 8 riviä.
