fix: prevent confirm dialog buttons from being unreachable on mobile with long text (#8746)

## Summary

Fix confirm dialog buttons becoming unreachable on mobile when text
contains long unbreakable words (e.g. content-hashed filenames with 100+
characters).

/>


## Changes

- **What**: Added `overflow-wrap: break-word` and `flex-wrap` to both
confirm dialog systems so long words break properly and buttons wrap on
narrow screens.
- `ConfirmationDialogContent.vue`: Added `overflow-wrap: break-word` to
the existing scoped style and `flex-wrap` to button row.
  - `ConfirmBody.vue`: Added `break-words` tailwind class.
  - `ConfirmFooter.vue`: Added `flex-wrap` to button section.

## Review Focus

Minimal CSS-only fix across both dialog systems (legacy
`dialogService.confirm()` and newer `showConfirmDialog()`). No
behavioral changes.
