fix(hls): pre-increment upload counter so it ticks through N of M

Previously the lambda set HlsPublishState.Uploading(done=uploadsDone)
before running the upload and incremented after. So while upload #1 was
actually in flight the state said "0 / 5 done", and StateFlow conflation
ate the post-upload increment before the UI could paint it — the counter
appeared stalled until the next rendition's onProgress flipped state
back to Transcoding.

Pre-incrementing means `done` now represents "working on item N of M"
rather than "N already finished, N+1 silently in flight", so the first
upload displays as "1 of 5" and each subsequent upload ticks to 2, 3,
4, 5 visibly. The earlier "done" wording existed to disambiguate 0/N
from a stalled bar; with pre-increment we never show 0/N, so the string
drops "done" and reads as the cleaner "Uploading X of Y".

Confirmed via logcat on device: R1 sinkFinish=5669ms, R2 sinkFinish=6343ms
— the "phantom upload" between R1 encoding and R2 encoding really was
the R1 combined upload; the counter just wasn't reflecting it.
