chore: dockerignore spec.ts files

The expense Total Amount, per-person "Who paid", and settlement amount
inputs used type="number" with a bare parseFloat. On desktop the number
input normalized comma→dot for free, but mobile keyboards drop the comma
before onChange fires, so parseFloat("39,99") silently became 39.

Switch the three inputs to type="text" inputMode="decimal" and normalize
comma→dot in their onChange handlers, matching the pattern already used
by the other budget inputs (BudgetPanelInlineEditCell, BudgetPanelAddItemRow,
DashboardPage). Both comma and dot now work on every device.

Closes #1256
