declaring a long timeout was giving a shorter one

Bun stores a per-request timeout in ONE BYTE. anything above 255 seconds
clamps to 255 — so a plugin declaring a generous 1800 got a SHORTER
timeout than one declaring nothing at all, which falls through to 0 and is
unlimited. the line meant to fix this is what armed it.

that is what killed every long transcription. 1800 became 255, the upload
took a second, the connection dropped at 4m16s, and whisperx went on and
finished into a dead socket. every time, all night, while three separate
fixes above it were already live and correct.

six plugins declare more than 255 and all six were getting 255:
transcribe, email and music at 1800, jellyfin at 3600, minesweeper and
photos at 600. fixed here rather than by deleting the declaration from one
router, because the other five have the same bomb.

anything Bun cannot represent becomes 0. a plugin asking for longer than
Bun's maximum is asking for "do not cut this off", and 0 is the only value
that means it.
