Rebuild: drop NUL from batches; chunk deadline 180 s

A file name with a NUL ("…Brutal Erpresst.ra\u0000…") failed every
batch of range 155595 (HTTP 500, jsonb: \u0000 cannot be converted to
text), so the range looped. fromWire drops NUL from every string.

The chunk deadline was given up 258 times in 3 hours at 300 s (~1.4 a
minute, each holding a connection for 5 minutes): 180 s.
