fix: remove delete button from list view — use detail page instead (#232)

The client-side lastInSeriesIds computation only sees the current page
of entries (20 at a time), producing false positives when the true last
voucher is on a different page or in a different fiscal period.

Delete is now only available from the detail page (/bookkeeping/[id])
where is_last_in_series is computed server-side from the full dataset.
