Subject: [PATCH] fix(ui): log-fallback warning is a toast, not a blocking
 alert()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

alert() in Electron halts the renderer main thread until the user
clicks OK — the upload table, status bar and progress all freeze.
During a 170-file batch the dialog popped up mid-upload and froze
everything for however long the user took to dismiss it (which is
why stats updates lagged to one every 3-5s instead of the usual 1s
cadence).

Replaced with the same showCopyToast used elsewhere, with an 8s
duration so the message is still readable. showCopyToast now accepts
an optional durationMs argument.
