Jake bc1ae3968e fix(paste): hide preview overlay before Ctrl+V to avoid Wayland focus race
Phase H landed the transcription preview overlay. Phase C landed auto-paste.
With both enabled the combo is broken on Wayland compositors (KWin, Mutter):
the overlay is always_on_top + visible at the moment paste_text fires its
Ctrl+V keystroke, and the compositor resolves the key to the topmost visible
window — which is the overlay, even though we built it with focused=false.
Net result: the transcript pastes into Kon instead of whatever app the user
was actually dictating into.

Fix, mirroring OpenWhispr's PR #246 shape: before trigger_paste_keystroke,
hide the transcription-preview window if it exists and is visible, then
sleep PREVIEW_HIDE_SETTLE_MS (80ms) so the compositor recomputes focus onto
the previously-focused app. No reshow — the user's confirmation is the text
appearing in the target app, not a fading overlay. The 80ms is enough on
KWin and Mutter; tunable if it shows up differently on other compositors.

paste_text now takes the tauri::AppHandle so it can reach the preview
window. Frontend invocation signature is unchanged (Tauri injects the
handle; the JS call site still passes { text }).
