CMD_SEND_RAW_DATA (0x19) was passed the encoded MeshCore route descriptor
(e.g. 0x41 for a 1-hop 2-byte-hash route), but the v1.15 companion firmware
raw-data handler treats the path byte as a legacy literal hop count, not an
encoded descriptor. It misread 0x41 as "65 path bytes" and rejected the
command (ERROR: Unsupported command), so media fetch always failed while
normal messaging worked.
- Add ContactRouteCodec.toLegacyRawPath() converting encoded descriptor +
path into legacy format (literal hop count + first byte of each hop hash).
- Apply it in ConnectionProvider.sendRawVoicePacket, the single chokepoint
all raw media (voice/image fragments, swarm, route probes) flows through.
- Pace served fragments 350ms apart to avoid firmware "ERROR: Table full"
when bursting many raw packets.
- Tests for the descriptor conversion.

Replace hardcoded English strings in 32 Dart source files with l10n
references. Covers settings labels, UI actions, map/SAR features,
device config, notifications, profiles, spectrum scan, and status
messages for sl, de, hr, pl, es, fr, it, el, ru, tr, uk, zh, pt.
Move BLE communication layer (command queue, frame parser/builder,
protocol constants, data models) into a standalone reusable Dart package
at ../meshcore_client. App model files become thin re-export wrappers,
keeping all existing consumers working without import changes.
