#1 Triage 'Save & mark paid' now marks the invoice paid directly (categorize +
markInboundPaid with the entered reference) instead of opening the pay dialog
and leaving it unpaid. Removed the PayModal chain.
#2 Cost side missed captured incoming invoices: the query required
currency='CHF', but email/upload invoices often have a null currency →
silently excluded. Now include null-currency rows (treated as the report
currency). Also replaced COALESCE(invoice_date, created_at) with a split
date filter (invoice_date BETWEEN, else created_at range) to avoid the
mixed date/timestamp comparison risk on Postgres. Same fix in the ledger
export (buildPostings).
