MsprgandClaude Fable 5.1 552276c75f pm5: hw bwm powersave
New `hw bwm powersave [on|off]` (CMD_PM5_BWM_POWERSAVE 0x0181) shows or
sets the ESP's persisted power-save switch (companion Proxmark5_BWM_esp32
PR: DFS, light sleep and slow advertising after a 30 s fast phase, or
the stock always-on behaviour), so the two can be A/B measured and the
saving turned off when chasing a link problem. `hw status` prints the
state next to the BWM firmware version.

Both module queries in `hw status` are time-bounded (version 2 x 800 ms,
power save 300 ms): a module that is silent, or a firmware without the
command, cannot push the report past the client's timeout.

Verified on hardware: state read/set/persist across an ESP reboot,
`hw status` after 4, 15 and 40 s idle in power-save mode and after 6 s
idle with it off.
