Fleet sync: Municipalities + Tariffs + TariffPeriods

Mirror the customer-side rate hierarchy (Municipality → Tariff →
TariffPeriod) to the central DB, scoped by CustomerId.
Per-municipality rate structure is preserved exactly as customers
configure it locally — each tariff still references its municipality
and carries its own per-period TOU rates.

Backend
- New fleet entities: FleetMunicipality, FleetTariff, FleetTariffPeriod.
  Composite PKs (CustomerId, Id) like Sites/Devices so two customers'
  rate trees never collide. FleetTariff has a real FK to
  FleetMunicipality on (CustomerId, MunicipalityId); FleetTariffPeriod
  cascades from its FleetTariff parent.
- Two new push batch types: "municipalities" (full set) and "tariffs"
  (full set with periods nested inside each tariff). Push order per
  tick: sites → devices → municipalities → tariffs → measurements.
- FleetIngestService dispatches the new types. Municipalities upsert
  by (CustomerId, Id). Tariffs run inside a single transaction per
  batch: upsert the tariff row, DELETE all periods for that tariff,
  INSERT the new set — atomic period replacement matches the
  customer-side UpsertTariffRequest semantics.
- FleetPushState gains ResourceMunicipalities + ResourceTariffs
  constants so the per-resource cursor/backoff state has slots for them.
- FleetQueryService.GetCustomerDetailAsync now includes municipalities
  and tariffs (with periods, with municipality name joined client-side
  from the lookup dict). New DTOs: FleetMunicipalityViewDto,
  FleetTariffViewDto, FleetTariffPeriodViewDto.
- AdminDbContext migration AddFleetRates creates the three tables and
  their indexes/FKs.

Frontend
- Customer detail page gains a "Tariffs (N)" tab. Each tariff renders
  as a collapsible card with its municipality, active flag, effective
  window, default rate / fixed charge / VAT, and an inline period
  table (Period name, day-of-week bitmask formatted as MTWTFSS, start,
  end, rate). Empty state when no tariffs synced yet.

Verified end-to-end on the dev host
- Created "Phase23 Test City" municipality + "Domestic TOU" tariff
  with two periods (Peak weekdays 17:00-20:00 @ 3.75, Off-Peak
  weekends 00:00-23:59 @ 1.20) on the Client.
- Within one push tick (~20s) all three rows landed on Admin:
  fleet.Municipalities (1), fleet.Tariffs (1), fleet.TariffPeriods (2).
- /api/fleet/customers/{id}/detail returns the full tree with
  municipality name resolved.

Tests: 61/61 still passing.

Design doc (FLEET-DESIGN.md §11) updated — tariff sync row marked
shipped, cross-customer cost compute flagged as the natural next step.
