win 2a7b731484 feat(finance): implement Phase 1 core P&L service + wire into dashboard

- Add internal/service/finance/types.go: AssetType enum, param/result structs
- Add internal/service/finance/service.go: Service interface, read-only ctor
- Add internal/service/finance/query_user.go: QueryUserProfitLoss (4 fan-out scans)
- Add internal/service/finance/query_activity.go: QueryActivityProfitLoss (4 fan-out scans)
- Add internal/service/finance/service_test.go: 22 integration tests (all pass)
- Wire finance.Service into admin handler (admin.go)
- Replace dashboard_activity cost scan with finance.Service call (D-09: value_cents single source of truth)
- Revenue/gamepass/draw-count scans unchanged; response schema fully compatible

Accumulated Context

Decisions

Decisions are logged in PROJECT.md Key Decisions table. Recent decisions affecting current work:

Init: Fan-out + in-memory merge query pattern chosen (avoids Cartesian product JOINs)
Init: Read-only DB routing enforced — constructor injects DbR only, no GetDbW() in package
Init: All existing finance.* utilities (IsGamePassOrder, ComputeProfit, etc.) must be reused, not re-derived
Init: Phase 2 (Fragment breakdown) requires schema verification of fragment_synthesis_logs join path before implementation

Pending Todos

None yet.

Blockers/Concerns

Phase 2: fragment_synthesis_logs join path and cost formula not yet verified — requires schema review during Phase 2 planning
Phase 1: SQLite test compatibility for CAST(AS SIGNED), GREATEST(), LIKE 'GP%' — must use Go-layer helpers or conditional SQL paths in integration tests
