M5: Blazor dashboard (MudBlazor + ApexCharts)

- MudBlazor theme (dark default) + responsive drawer/appbar layout + nav.
- DashboardService read model: KPIs with period-over-period deltas, category breakdown,
  "what cost more/less" difference view, monthly trends.
- Pages: Overview (KPI cards + DeltaChip + donut + difference table), Trends (range-select
  bar chart), Meters (list + source status), Import (load reference dataset + CSV dry-run
  preview), Admin (energy types, tariffs). Charts isolated into components to avoid the
  ApexCharts/MudBlazor Color/Format name clashes.
- ReferenceDataImporter: one-click load of all four sheets as a starter dataset (meters,
  tank, tariff history, category memberships) — bundled sample CSVs copied to app output.
- End-to-end render test: import creates meters + consumption; overview/meters/trends/
  import/admin pages all return 200 with KPI cards rendered.

92 tests green (56 Core + 36 integration).

Deferred to polish: dedicated PV & oil/consumable panels, meter-detail page, full admin
CRUD, prev-year trend overlay.

M2: German CSV importer + reconciliation of all 4 fixtures

- German-dialect scalar parsers in Core (GermanNumber/Money/Date, ValueCell):
  decimal comma, thousands dot, unit suffixes, € currency, both date shapes.
- Declarative MappingProfile + RowClassifier (skip summary/blank/all-zero rows) +
  CsvImporter (CsvHelper) staging readings/events/manual-costs, with auto swap
  detection on register decreases and month-end anchoring for interleaved oil dates.
- Four built-in ReferenceProfiles (Strom/Wasser/Heizöl/Kosten).
- ImportService: commit as revertible import_batch + wholesale consumption recompute
  per affected meter (NormalizationService/MeterConfigFactory), revert by batch.
- Reconciliation tests: all 4 CSVs match the sheet's own columns within tolerance
  (electricity 5 meters + Netz Einsparung, water swap→12, oil tank incl. deliveries +
  burner hours, cost category totals). Commit/revert round-trip verified on Timescale.

69 tests green (53 Core + 16 integration).

Known follow-up (polish): historical imports can contend with the 30-day compression
policy's background job; tests pause it. Consider retry-on-deadlock or deferred
compression for large historical imports in production.
