ruv 3959fabf31 feat(rust): host-side decode for ADR-018 byte 18-19 (ADR-110 closure)
Parse the C6 firmware's HE PPDU type + bandwidth/flags from ADR-018
bytes 18-19 (previously discarded as _reserved). Adds two types to
CsiMetadata: ppdu_type (HtLegacy/HeSu/HeMu/HeTb/Unknown) and
adr018_flags (bw40/stbc/ldpc/ieee802154_sync_valid).

Pre-ADR-110 firmware sends zeros which round-trip as HtLegacy +
default flags — fully backwards compatible.

6 new deterministic unit tests:
- Pre-ADR-110 backwards compat
- HE-SU / HE-MU / HE-TB decode
- Unknown PPDU byte -> Unknown
- All-bits-set flags round-trip
- PpduType byte round-trip

Result: 122 wifi-densepose-hardware tests pass, 0 fail. Host decoder
now matches the firmware encoder bit-for-bit — HE-LTF metadata path
works end-to-end the moment an 11ax AP is in range.
