fix(transactions): keep saved-filter delete button visible on touch and confirm before deleting (#648)

## Problem

The delete button on a saved filter was only revealed on **hover**. On
desktop that's fine, but on touch devices the button is invisible yet
still clickable, so users kept deleting saved filters by accident. There
was also no confirmation step before a filter was deleted.

## Changes

- **Always visible on touch** — the hover-reveal is now gated behind
`@media (hover: hover)`. On hover-capable devices the trash icon still
appears only on hover; on touch devices (`hover: none`) it stays
visible.
- **Confirm before deleting** — deleting a saved filter now opens an
`AlertDialog` confirmation ("Are you sure you want to delete "…"?"),
matching the existing delete-confirmation pattern used across the app.
Cancel/Escape dismiss without deleting.

## QA

Tested end-to-end in a real browser (mobile emulation, `hover: none`):

- Desktop (`hover: hover`): delete button computes `opacity: 0` until
hover ✓
- Touch (`hover: none`): delete button computes `opacity: 1`, visible
without hover ✓
- Tapping the trash icon opens the confirmation dialog with the correct
filter name ✓
- **Cancel** keeps the filter (verified in DB) ✓
- **Delete** removes it (verified in DB) ✓
