fix: create expense report immediately — remove broken confirmation gate

The old flow required a "confirm" reply after showing a parsed-receipt
table, but that follow-up dispatch call carries no receipts (they only
exist in the /upload context). The confirmation gate was architecturally
broken: the second turn would always create nothing.

Fix: create the expense sheet immediately when receipts are present.
Byte-exact and semantic duplicates are auto-skipped; the count of
skipped items is reported in the success message. The report is always
created in Odoo as a draft so users can review amounts and submit
manually via Odoo > Expenses.
