fix: miler assignment lifecycle, pickup hub resolution, and hyperlocal delivery

Bugs found during live Coimbatore testing against production:

- GetMilerAssignments returned every assignment ever made to a miler with
  no status filter, so weeks-old Rejected assignments still showed up as
  actionable in the app. Now filters to Assigned/Accepted only.
- AcceptMilerAssignment overwrote assignmentstatus unconditionally, letting
  a stale Rejected assignment be silently reactivated (and pushing its
  booking back to Pickup_Scheduled). Now 400s unless currently Assigned,
  reporting the actual status.
- RejectMilerAssignment read `reason` from the query string instead of the
  JSON body, contradicting the API contract and every sibling endpoint.
- BookingPickupComplete resolved the origin hub via db.First(&hub) with no
  Where clause — i.e. the lowest hub ID in the table, unrelated to the
  booking or miler. Now uses the miler's own MilerProfile.Hubid, falling
  back to the old behaviour with a warning only when unassigned.
- No code path ever set a consignment to Out_for_Delivery, making
  MilerDeliverConsignment unreachable. BookingPickupComplete now goes
  straight to Out_for_Delivery when pickup and delivery pincodes share a
  3-digit postal-area prefix (same-miler hyperlocal), reusing the
  hubPincodePrefix convention. Cross-hub still lands at Inwarded_at_Hub.

Also allow https://app.doormile.com in CORS, and drop a stray Windows-path
log file that was committed by accident.
