Persist named backtest-strategy presets so a staking config (bankroll, min-score, stake rule, flat/percent/Kelly params) can be saved, listed, loaded back into the form, and deleted. The per-run date range is not part of a preset. - Domain: SavedStrategy record (name trimmed + bounded to 80 chars, Create() factory) wrapping the pure BacktestStrategy. - Persistence: SavedStrategyEntity + config (TEXT decimals, unique case-insensitive NOCASE index on Name), repository, mapping, and a hand-trimmed AddSavedStrategies migration (additive — only the new table). Case-insensitive names mean save-by-name overwrites instead of creating near-duplicates. - Application: SaveStrategyUseCase (upsert by name, keeps Id+CreatedAt) + DeleteStrategyUseCase. - UI: presets panel on the Backtest page (load/save/delete) + service methods; fraction<->percent round-trip; en/ru resx. - Fix: pin Sports.Code as ValueGeneratedNever — it is the bookmaker's natural sport id, not an autoincrement surrogate. Corrects long-standing model-snapshot drift; the snapshot is regenerated to match the DB. - 25 tests across all four layers: domain validation, real-SQLite round-trip incl. case-insensitive lookup/uniqueness, the upsert use case, and the service percent mapping.
