Reverts the earlier per-rate pricing_mode column in favor of extending Lunar's existing charge_by field (cart_total/weight) with a third "live" option, gated by a SupportsLivePricing capability check on the driver. Adds a shared ResolvesFixedPricing trait so any carrier driver can fall back to Lunar's normal price-break resolution, matching the vendor ShipBy driver's own charge_by handling instead of introducing a separate mechanism. Also fixes an incorrect Get() path in the admin form that silently hid the new "live" option.
Registers ShippingServiceProvider (carrier config, driver/fulfillment bindings, Rates page override) and wires the shipping admin surface into CorePlugin: dynamic carrier dropdown on Shipping Method create/edit, a "Create Shipment" order action resolved generically by carrier, and a Pickup Manifests page for carriers that support manifest batching.
Box Now rate driver (fixed pricing only — no live pricing API) and fulfillment service (delivery request creation, label printing, cancellation). Unlike ACS, Box Now books courier pickup automatically on delivery request creation, so no manifest/pickup-list step is implemented. Storefront locker selection is not yet built; createShipment() expects the chosen locker's locationId to be supplied by the caller.
ACS rate driver (live price quotes via ACS_Price_Calculation, cached postcode-to-station lookups) and fulfillment service (voucher creation, label printing, end-of-day pickup manifest). Adds a per-rate pricing_mode column so admins can choose live API pricing vs. a fixed price on ACS-driven shipping rates, surfaced via a custom Rates page.
Completes the carrier-agnostic shipping abstraction (CarrierFulfillmentInterface, SupportsManifestBatching, Shipment model) with the result type SupportsManifestBatching::issueManifest() returns.
