v0.3.6 - Wake/power-on works on Eletta Explore

Wake / power-on now works on Eletta Explore (DL-striker-cb).

Captured frames (issue #1, thanks @MrSpongy) showed the synthesized wake is ignored by the machine while the app's wake works - with identical structural bytes. The only difference: the app appends a 4-byte device signature after the timestamp (e.g. 00 d3 2f 8c) that the built frame lacked. That same signature is why verbatim beverage replay already worked but a synthesized wake did not.

The integration now learns the app's power-on frame and replays it verbatim (fresh timestamp only), exactly like beverages - and persists it across restarts.

To enable it

Power the machine on once from the official Coffee Link app (with HA running). Home Assistant captures that frame; from then on the Wake button replays it, including after a restart.

The PrimaDonna Soul (DL-millcore) wake is unchanged. 35 unit tests pass.
