Commit 47a603b

Each expense claim is now allocated purely by its paid date (and unpaid by item expense date), but the split between “Nov 2023–2024” and “Nov 2024–2025” is now based on precise 1‑year steps from the selected range (typically “current date minus N years” → “current date”)
The Expense Summary columns and the detailed payee breakdowns now align exactly with the intended AGM‑year boundaries defined by the current date range selected

walks: ensure morning, evening, unfilled slots add up to total walks on programme for the selected year
socials: Only list social events for the last year in the detail table
