fix(parcels): SAVEPOINT around velocity compute → не abort outer tx (#154)
Production POST /parcels/{cad}/analyze падает с 500:
  sqlalchemy.exc.InternalError: (psycopg.errors.InFailedSqlTransaction)
  current transaction is aborted, commands ignored until end of transaction block

## Root cause

`compute_velocity()` SQL fails (probably на cad's без conkurrentов / sparse
sale_graph data) → exception caught в try/except → НО db.rollback() отсутствует
→ transaction остаётся в aborted state.

Следующая query (_geotech_risk на line 828) пытается выполниться → крашится
с InFailedSqlTransaction.

## Fix

Wrap velocity в `with db.begin_nested()` — SAVEPOINT pattern (consistent
with PR #124 pzz_loader fix). Failure внутри savepoint:
- Rollbacks ТОЛЬКО savepoint
- Outer transaction остаётся clean
- Subsequent queries (_geotech_risk и пр.) работают

Pattern matches feedback_subagent_delegation audit recommendation для
in-loop / per-section exception handling.

## Impact

POST /parcels/{cad}/analyze больше не 500 при velocity failure. Возвращает
`velocity: null` + остальные fields normal.
