Name the abort cause (size vs time) instead of a generic "mirror limit"

The #482 abort log and per-slot status were reworded to a generic "mirror
limit" once the size cap could also drive them, which dropped the cause. Add
an hts_mirror_limit enum and a back_mirror_limit() helper that reports which
cap overran its grace; back_checkmirror() now delegates its hard-stop decision
to it (removing the duplicated grace conditions), and the back_wait abort loop
uses it to log "size limit reached" / "time limit reached" and stamp the slot
"Mirror Size Limit" / "Mirror Time Out". This restores the precise wording -E
had before and gives the size path its own.

back_maxsize_grace keeps no floor, unlike the time grace: a size overrun
should abort promptly rather than let more bytes through. Documented inline.

Dropped the `--found bigtrickle/p0.bin` check from the test: the #482 hard
abort truncates a large file that is being re-fetched when the cap trips
(reproducible on master's -E path too), so p0.bin is legitimately 0 bytes on
many runs. The wall-clock bound is the discriminating assertion; the "giving
up" line fires for the unfixed engine as well.
