## Summary
Improves the transaction actions menu on mobile:
- **Tap-to-show tooltip instead of a modal** — when the Analysis button
is tapped with no filter applied, it now shows the same tooltip used on
desktop ("Apply a filter to enable this button") via a controlled Radix
tooltip, instead of opening a separate modal dialog.
- **Always show the "Analysis" label on mobile** — previously the mobile
button was icon-only, which made it hard to understand. It now shows the
icon + label like desktop.
- **Move "Add transaction" into the more-actions dropdown on mobile** —
frees up horizontal space so the Analysis label fits. On desktop the
standalone Add transaction button is unchanged.
## Notes
- Reuses the existing `Add transaction` translation key (already in
`lang/es.json`).
- Removed the now-unused `Dialog` import/markup.
## Test plan
- [ ] On mobile, tap Analysis with no filter → tooltip appears on tap,
dismisses on tap outside.
- [ ] On mobile, the Analysis button shows its label.
- [ ] On mobile, "Add transaction" appears in the more-actions (⌄)
dropdown.
- [ ] On desktop, behavior is unchanged (hover tooltip, standalone Add
transaction button).
