Krzysztof kuhy Rudnicki 434cb7587e Test bt_adapter.sh to 98.55%; line 97 is unreachable by construction
Third of the 16 untested fixes/lib libs, and the first that does NOT come
off the allowlist. 68/69 = 98.55%, up from 45/69. The remaining line is
not a missing test:

  PS4='+TRACE:${BASH_SOURCE##*/}:${LINENO} ' bash -x

shows bash attributing the whole multi-line dbus-send assignment in
_services_resolved to line 100, and never emitting line 97 at all. Line 97
is the OPENING line of a backslash-continued statement; kcov instruments
it, bash never attributes a statement to it. That is defect (a) in
docs/kcov-under-report.md -- a wrong denominator -- and no test can move it.

continuation_lines() in shell_coverage_lines.py already excludes such lines,
but only detects them by tracking QUOTE state, so a line ending in an
unquoted backslash slips through. Fixing that is deliberately left out of
this commit: it changes the denominator for every measured lib, and if it
regresses one of the libs now gated with no exemption, reverting a mixed
commit would throw away these tests too.

Scope of the problem, measured rather than guessed -- backslash
continuations are confined to the bluetooth family: bt_audio.sh 10,
bt_adapter.sh 7, bt_pairing.sh 3, pacman_hook_stall_summary.sh 2, and ZERO
in the other 12 remaining libs. So this caps bt_audio.sh next and then stops
mattering.

Also replaces the harness's _t_only_path with _t_hide. _t_only_path dropped
PATH to $FAKE_BIN alone, which hid grep, head and sort as well as the tool
under test -- so the "usbreset is not installed" case died in a cascade of
"command not found" and passed for the wrong reason instead of exercising
the fallback. _t_hide rebuilds PATH from symlinks to every real executable
except the named ones; verified directly that command -v usbreset is then
empty while grep and head still resolve.

bt_report.sh (37/37) and bt_pairing.sh (65/65) re-measured at --min 100,
both exit 0, so neither cleared lib regressed.
