Consolidate single-action controllers into resource controllers

Merge 11 single-action controllers into their parent resource controllers:
- Invoice: send, sendPreview, clone, changeStatus -> InvoicesController
- Estimate: send, sendPreview, clone, convertToInvoice, changeStatus -> EstimatesController
- Payment: send, sendPreview -> PaymentsController

Extract clone and convert business logic from controllers into services:
- InvoiceService: add clone(), changeStatus()
- EstimateService: add clone(), convertToInvoice(), changeStatus()

Previously this logic was inlined in controllers (~80-90 lines each).
