The reported "upload doesn't work, file never appears" was two things, both
hit when uploading config files like .env:
1. Single-file upload used overwrite=false and dead-ended on "Already
exists: .env — rename or remove the existing file first." with no way to
replace the file. Now a conflict opens an Overwrite confirmation dialog
(mirroring the copy/paste conflict flow) that retries with overwrite=true.
2. .env (and any dotfile) is hidden, so even a successful upload stayed
invisible unless "Show hidden" was on. After an upload whose name/path
has a dot-segment, "Show hidden" is now auto-enabled so the file shows.
The single-file upload mutation now takes {file, overwrite}; folder upload
(already overwrite=true) also auto-reveals hidden results.
Frontend-only; all 3 images rebuilt+pushed 0.37.5.
