fix(radio): consume upstream lora-phy pre-command BUSY check

Pick up the proper fix from our fork at swaits/lora-rs@fix/sx126x-busy-race:
move the ready check from *after* to *before* each SPI op per the
Semtech manuals (SX1261/2 §8.3.1, LR1121 UM §3 / §3.5, LR1110 DS
§1.2.5) and rename InterfaceVariant::wait_on_busy to wait_until_ready.

Firmware side is surgical: since the upstream fix keeps the
GenericSx126xInterfaceVariant::new signature at 5 args (no DelayNs
threading), there is nothing to change in the four nRF / ESP / RP2040
board files beyond a one-line comment rename (wait_on_busy ->
wait_until_ready) in the BUSY-pullup comment on the two nRF boards.

Wire in the [patch.crates-io] override pointing at ../../lora-rs/lora-phy,
bump the dep spec to the pre-release 3.0.2-alpha that matches the fork,
and enable the defmt-03 feature that upstream moved behind a gate
between 3.0.1 and the fix branch.

TODO.md rewritten to track the new approach: PR body template with
verbatim citations from all three Semtech chip manuals (SX1261/2,
LR1121 UM, LR1110 DS) plus the SX1276 pin table confirming the family
has no BUSY line.

No change to firmware behavior beyond picking up the upstream fix,
which takes first-TX-after-boot success from ~50% to 20/20 on the
Seeed Wio Tracker L1 repro board.
