cbd-web: drop the unreachable capture-delete confirmation

delete_needs_confirmation only ever returned true for /captures paths,
and /captures stopped existing when saved queues, bookmarks, and captures
folded into the single /crabidy provider. So the y/N dialog could not
open, the web client already deleted immediately, and its comment
claiming to mirror the TUI described an arrangement neither client had.

Removed rather than re-pointed at /crabidy: a delete there drops the
metadata toml only, never the shared store audio, which survives and
resurfaces under /orphans — so there is little to guard. Both clients now
behave the same, which is what the docs describe.

Gone with it: the Dialog::ConfirmDelete variant, the ConfirmDialog
component and its keyboard handler, the test, and the two CSS rules only
that dialog wore (.danger-dialog and the solid .danger button;
.ghost.danger stays, three row actions still use it).

Verified: clippy clean for wasm32 (where `mod app` actually compiles) and
native, 12 cbd-web tests pass, and the trunk bundle builds.
