Bridge.writeFile had the same URL-length trap saveFile did: a large
auto-backup base64'd into a single cmd://file/write URL blew past
WebView2's ~2MB navigation cap, so backups of big vaults failed
silently (or blanked the page) — for BOTH the manual "Backup now"
button and the silent scheduled run.
- writeFile now streams payloads over ~1MB in chunks (reusing the same
file/chunk transport as saveFile), committed via a new
file/write-commit. Delphi shares the decode+write logic through a new
WriteDecodedFile helper and the existing FFileSaveChunks buffer.
- runAutoBackupNow(silent): the manual run shows the busy overlay
("Reading vault… N/total" → "Encrypting backup…" → "Writing file… N%")
since a 20MB backup takes ~30s; the scheduled on-unlock run passes
silent=true (no overlay, but still chunked so it no longer fails on
large vaults).
- Fixed the "Backup now" click handler passing the click Event as the
silent arg (truthy → would have suppressed the spinner and swallowed
errors); wrapped in () => runAutoBackupNow().
- Pre-sync backup benefits from the chunked writeFile automatically.
Rebuild: BuildAssets + F9 (UMainForm.pas changed).
